Small and medium-sized businesses (SMBs) seek to derive value from their data without heavy infrastructure investment, and Amazon Athena offers a simple yet powerful solution. As a serverless query service, Athena allows teams to run SQL queries directly on data stored in Amazon S3, eliminating the need for provisioning servers, setting up databases, or managing ETL pipelines.

Many SMBs use Athena to generate fast insights from CSVs, logs, or JSON files stored in S3. For example, a healthcare provider can use Athena to analyze patient encounter records stored in S3, helping operations teams track appointment volumes, identify care gaps, or monitor billing anomalies in real time.

This guide will go deeper into how Athena works, how it integrates with AWS Glue for automated schema discovery, and how SMBs can get started quickly while keeping costs predictable and usage efficient.

Key takeaways: 

• Run interactive SQL queries directly on Amazon S3 without managing any servers or infrastructure.
• Only pay for the data scanned, making it cost-effective for SMBs with varying workloads.
• Works seamlessly with AWS Glue, IAM, QuickSight, and supports multiple data formats like Parquet, JSON, and CSV.
• Ideal for log analysis, ad-hoc queries, BI dashboards, clickstream analysis, and querying archived data.
• Read-only access, no DML support, performance depends on partitioning and query optimization.

What is AWS Athena and why does it matter for SMBs?

Amazon Athena is a serverless, distributed SQL query engine built on Trino (formerly Presto) that lets businesses query data directly in Amazon S3 using standard SQL, without provisioning infrastructure or building ETL pipelines.

It runs queries in parallel across partitions of business data, which drastically reduces response times even for multi-terabyte datasets. Its schema-on-read model means SMB teams can analyze raw files like CSV, JSON, or Parquet without needing to ingest or transform them first.

Key technical benefits for SMBs include:

• Efficient querying with columnar formats: When SMBs store data in Parquet or ORC, Athena scans only the relevant columns, significantly reducing the amount of data processed and cutting query costs.
• Tight AWS integration: Athena connects to the AWS Glue Data Catalog for automatic schema discovery, versioning, and metadata management, allowing SMBs to treat their Amazon S3 data lake like a structured database.
• Federated query support: SMB teams can run SQL queries across other AWS services (e.g., DynamoDB, Redshift) and external sources (e.g., MySQL, BigQuery) using connectors through AWS Lambda, enabling cross-source analytics without centralizing all their data.
• Security and compliance: Access is controlled via IAM, and all data in transit and at rest can be encrypted. Athena logs queries and results to CloudTrail and CloudWatch, helping regulated industries meet audit requirements.

Example: A diagnostics lab stores lab results in Parquet files on Amazon S3. With Amazon Athena + AWS Glue, they create a unified SQL-accessible view without loading data into a database. Analysts query test volume by region, check turnaround time patterns, and even flag anomalies, all with no infrastructure or long reporting delays.

The bottom line? Amazon Athena gives SMBs the power of big data analytics—on-demand, with no overhead—making it ideal for lean teams that need insights fast without building a data warehouse.

How to get started with AWS Athena? step-by-step

To get started, businesses need to organize their data in Amazon S3, define schemas using AWS Glue Data Catalog, and run queries using standard SQL. With native integration into AWS services, fine-grained IAM access controls, and a pay-per-query model, Athena makes it easy to unlock insights from raw data with minimal setup. It's ideal for teams needing quick, cost-effective analytics on logs, reports, or structured datasets.

Setting up AWS Athena is relatively straightforward, even for businesses with limited technical expertise:

1. Set up an AWS account

To begin using Amazon Athena, an active AWS account is required. The user must ensure that Identity and Access Management (IAM) permissions are correctly configured. Specifically, the IAM role or user should have the necessary policies to access Athena, Amazon S3 (for data storage and query results), and AWS Glue (for managing metadata). 

It's recommended to attach managed policies like AmazonAthenaFullAccess, AmazonS3ReadOnlyAccess, and AWSGlueConsoleFullAccess or create custom policies with least-privilege principles tailored to the organization’s security needs. These permissions allow users to create databases, define tables, and execute queries securely within Athena.

2. Create an S3 bucket for data storage

Before running queries with Athena, data must reside in Amazon S3, as Athena is designed to analyze objects stored there directly. This setup step includes bucket creation, data upload, and optimization for query performance.

Navigate to the Amazon S3 console and click “Create bucket.”

• Assign a globally unique name.
• Choose a region close to the workloads or users for latency optimization.
• Enable settings like versioning, encryption (e.g., SSE-S3 or SSE-KMS), and block public access if required.

Upload datasets in supported formats: Athena supports multiple formats, including CSV, JSON, Parquet, ORC, and Avro.

• For better performance and lower cost, use columnar formats like Parquet or ORC. 
• Store large datasets in compressed form to reduce data scanned per query.

Organize data into partitions: Structuring data into logical partitioned folders (e.g., s3://company-data/patient-records/year=2025/month=07/) enables Athena to prune unnecessary partitions during query execution.

This improves performance and significantly reduces query costs, as Athena only scans relevant subsets of data.

Set appropriate permissions: Ensure IAM roles or users have the necessary S3 permissions to list, read, and write objects in the bucket. Fine-grained access control improves security and limits access to authorized workloads only.

3. Set up AWS Glue Data catalog (optional)

AWS Glue helps SMBs manage metadata and automate schema discovery for datasets stored in Amazon S3, making Athena queries more efficient and scalable.

• The team creates a Glue database to store metadata about the S3 datasets.
• A crawler is configured to scan the S3 bucket and automatically register tables with defined schemas.
• Once cataloged, these tables appear in Athena, enabling immediate, structured SQL queries without manual schema setup.

4. Access AWS Athena console

Once the data is in Amazon S3 and cataloged (if applicable), the team navigates to the Amazon Athena console via the AWS Management Console.

• They configure a query result location, specifying an S3 bucket where Athena will store the output of all executed queries.
• This is a mandatory setup step, as Athena requires an S3 destination for query results before any SQL can be run.

5. Run the first query

With the environment configured, the team can begin querying data:

• In the Athena console, they select the relevant database and table, automatically available if defined in AWS Glue.
• They write a query using standard SQL to analyze data directly from Amazon S3.
• On executing the query via “Run Query,” Athena scans the underlying data and returns the results in the console and the designated S3 output location.

6. Review and optimize queries

As the team begins using Athena, it’s important to ensure queries remain efficient and cost-effective:

• Implement partitioning on commonly filtered columns (e.g., date or region) to reduce the amount of data scanned.
• Limit query scope by selecting only necessary columns and applying precise WHERE clauses to minimize data retrieval.
• Use the Athena console to monitor query execution time, data scanned, and associated costs, enabling optimization and proactive cost control.

7. Explore advanced features (optional)

Once the foundational setup is complete, SMBs can begin using Amazon Athena’s more advanced capabilities:

• Optimize with efficient data formats: Use columnar formats like Parquet or ORC to reduce scan size and improve query performance for large datasets.
• Visualize with Amazon QuickSight: Connect Athena to Amazon QuickSight for interactive dashboards and business intelligence without moving data.
• Run federated queries: Extend Athena’s reach by querying external data sources, such as MySQL, PostgreSQL, or on-prem databases—via federated connectors and AWS Lambda.

These features allow teams to scale their analytics capabilities while keeping operational overhead low.

Practical use cases for Amazon Athena in business operations

Amazon Athena is more than a business tool. It is a practical engine for answering real business questions directly from raw data in S3, without the delays of setting up infrastructure or ETL pipelines. 

For SMBs, it offers a fast path from storage to insight, whether you’re analyzing patient records in healthcare, transaction logs in retail, or system logs in SaaS platforms. Because it speaks standard SQL and integrates natively with AWS Glue and QuickSight, teams can start querying within minutes, with no heavyweight setup, and no data wrangling bottlenecks.

1. Log analysis and monitoring

Amazon Athena is ideal for analyzing server logs and application logs stored in Amazon S3. It allows businesses to perform real-time analysis of logs without needing to set up complex infrastructure.

Example: A retail SMB collects logs from its web servers, tracking user activity and transaction details. Using Athena, the business can query logs to identify trends such as peak shopping hours or common search queries. This data helps the company optimize its website for better user engagement and targeted promotions.

2. Data warehousing and business intelligence

Amazon Athena can be used as a lightweight data warehousing solution, particularly for SMBs that do not require the heavy infrastructure of a full-scale data warehouse. It integrates easily with Amazon QuickSight to deliver business intelligence (BI) dashboards and reports.

Example: A small e-commerce business uses Athena to run SQL queries on sales data stored in Amazon S3. The results are then visualized in Amazon QuickSight to track key performance indicators (KPIs), such as daily sales, revenue per product, and customer acquisition rates, allowing the business to make data-driven decisions.

3. Ad-hoc data queries

For businesses that need to quickly analyze large datasets without the overhead of setting up and maintaining a dedicated analytics system, Athena provides an efficient and cost-effective solution.

Example: A small marketing firm has large datasets containing customer demographics and campaign performance metrics. With Athena, the firm can run ad-hoc queries to analyze customer behavior and assess the effectiveness of different marketing campaigns in real-time, without needing a permanent infrastructure.

4. Clickstream analysis

Athena is a popular tool for analyzing clickstream data, which helps businesses understand user behavior on websites or apps. By querying clickstream data in real-time, companies can optimize user experiences and improve conversion rates.

Example: A media company collects clickstream data that tracks how users interact with its online content. Using Athena, the company can quickly query this data to identify which articles or videos are most popular, what content leads to longer engagement, and where users drop off. This allows the company to tailor content strategies to improve user retention.

5. Data archiving and backup analysis

Businesses often archive large amounts of historical data that may not be frequently accessed but still need to be searchable. Athena makes it easy to query these archives to retrieve specific data when needed.

Example: A healthcare provider stores patient records and historical treatment data in S3. Though this data is rarely accessed, it still needs to be searchable in case of audits or legal requests. Athena allows the provider to run quick queries on archived data, retrieving necessary records without the need for time-consuming data retrieval processes.

Amazon Athena’s versatility makes it an excellent tool for a wide range of use cases, from log analysis to financial reporting. Its serverless nature and cost-effective pricing model ensure that even SMBs with limited technical resources can harness the power of data analytics without the need for complex infrastructure.

‍

Cyberattacks are getting more frequent and more expensive. IBM’s most recent cloud security study reports that the average cost of a data breach has reached USD 4.35 million. In response, over half of global organizations are planning to boost investments in threat detection, incident response, and cloud security tools throughout 2025.

For small and mid-sized businesses (SMBs) in sectors like healthcare and fintech, the stakes are even higher. All it takes is one misconfigured access policy or exposed resource to trigger a costly security incident or regulatory fallout.

The good news is that AWS provides a flexible foundation for implementing strong, scalable defenses if the right controls are in place. That’s why more growth-focused SMBs are working with AWS partners like Cloudtech to build secure, compliant environments from the ground up. 

This article walks through the most important AWS cloud security practices for 2025, and how to implement them in a way that aligns with the risk profile, industry standards, and long-term goals.

Key takeaways:

• Security is not a one-time setup; it’s a continuous discipline: AWS provides the tools, but SMBs must define clear strategies and enforce controls as environments evolve.
• Misconfigurations are the biggest threat, and the easiest to prevent: With IAM policies, automated monitoring, and least privilege access, most breaches can be avoided before they happen.
• Smart automation is force multiplication for small teams: Tools like AWS Config, Amazon GuardDuty, and AWS Systems Manager help SMBs scale security efforts without scaling headcount.
• Cloud-native security doesn’t mean complexity; it means control: When implemented correctly, AWS makes it easier for SMBs to enforce governance, meet compliance, and respond quickly to threats.

Why do SMBs need a security-first AWS strategy?

AWS operates on a shared responsibility model, meaning Amazon secures the infrastructure, while customers are accountable for securing their data, configurations, and access policies.

Without a clear, well-documented strategy, SMBs often face preventable risks like open Amazon S3 buckets, over-permissive IAM roles, or outdated security groups. These gaps aren’t just technical oversights. They’re business liabilities that can lead to data breaches, compliance violations, and lost customer trust.

For industries like healthcare and fintech, the pressure is even greater. Regulations such as HIPAA and PCI-DSS require strict controls over data access, encryption, and audit trails. Falling short, even unintentionally, can result in heavy fines and reputational damage.

Establishing cloud security best practices from the start helps SMBs:

• Stay compliant with evolving industry regulations
• Reduce the risk of misconfiguration and unauthorized access
• Gain visibility into their cloud environment through monitoring and alerting
• Build a strong foundation that scales with business growth

For SMBs having limited IT teams or expertise, AWS partners like Cloudtech can help them implement the necessary AWS cybersecurity strategies in a way that fits their team size, risk profile, and industry requirements.

How can SMBs implement a security-first AWS strategy?

Unlike large enterprises, most SMBs don’t have the luxury of dedicated security teams or redundant systems. They move fast, manage lean teams, and prioritize innovation, especially in sectors like healthcare and fintech where demand is high and competition is fierce. Cloud platforms like AWS help level the playing field, but only if security keeps pace with growth.

In the early stages, it’s natural to focus on performance and delivery. But as environments expand with new workloads, more users, and tighter compliance expectations, security gaps can quietly emerge. Maybe a former contractor still has admin access. Maybe a key data store isn’t encrypted. They’re common side effects of scaling without a structured security plan. And when audits or incidents do arise, they tend to hit smaller businesses harder.

A security-first strategy helps SMBs get ahead of these risks. It brings clarity to what needs protecting, who needs access, and how to automate guardrails that support rather than slow down the business.

The following step-by-step strategy outlines how SMBs can achieve this using AWS-native tools, without overextending their teams or budgets.

1. Understand the shared responsibility model

Security in the cloud is a shared model. AWS secures the infrastructure of the cloud, while businesses are responsible for what they put in it. That includes user access, data classification, encryption settings, compliance configurations, and software-level protections. For SMBs in fintech and healthcare, this model directly impacts how they approach risk management, incident response, and audit readiness.

Real-world scenario: A healthcare startup launches a patient portal on Amazon EC2, assuming AWS manages encryption and access controls by default. However, without explicitly configuring IAM policies, enabling encryption at rest for EBS volumes, or setting up Amazon CloudTrail for audit logs, the environment remains exposed. This violates HIPAA and risks reputational damage in the event of a breach.

To operationalize the shared responsibility model:

• Map responsibilities by service: Use the AWS Shared Responsibility Model and align it with business architecture. For example, AWS manages Amazon RDS’s physical infrastructure. The SMB must enable encryption, rotate keys, and configure IAM policies for database access.
• Assign internal ownership: Create a responsibility matrix that maps each AWS service (e.g., Amazon S3, Amazon EC2, Amazon RDS, AWS Lambda) to a specific team or role, such as DevOps, compliance, or security engineering. This prevents accountability gaps.
• Standardize configuration baselines: Use AWS Config rules and AWS CloudFormation templates to enforce consistent security controls across environments (e.g., block public Amazon S3 buckets, enforce MFA for IAM users).
• Review regularly: As the stack evolves, review ownership and configuration at least quarterly to ensure no drift has occurred, especially after team changes, rapid scaling, or vendor integrations.

Understanding this model ensures that no one assumes AWS “has it covered” when, in reality, critical responsibilities like encryption, access control, and compliance reporting rest squarely on the business side of the fence.

2. Establish a formal cloud security strategy

Once the lines of responsibility are clear, the next priority is developing a formal cloud security strategy. Many SMBs, especially in regulated sectors like healthcare and fintech, spin up AWS environments quickly to meet demand, but without a guiding framework, risk and compliance gaps grow unnoticed.

A security strategy ensures consistency and accountability across teams, especially as infrastructure scales or regulatory pressure increases.

2. Establish a formal cloud security strategy

• Risk tolerance: Clarify how much risk the business can accept when choosing between speed, cost, and control. This informs architecture and vendor decisions.
• Compliance alignment: Map applicable standards like HIPAA, PCI-DSS, or SOC 2 to AWS configurations. For example, enable Amazon S3 encryption, enforce logging, and use private subnets for sensitive workloads.
• Team roles and ownership: Assign responsibility for identity, monitoring, key management, and remediation to avoid gaps during day-to-day ops or audits.
• Incident response workflows: Document how the team will detect and respond to threats, using AWS-native tools like Amazon GuardDuty, AWS CloudTrail, and AWS Systems Manager.

This document doesn’t need to be perfect from day one, but it does need to exist and evolve over time. Treat it as the team’s north star for scaling securely and making decisions that stand up to audits, not just deadlines.

3. Use strong identity and access controls

With a strategy in place, the next layer is precise access control. Identity and access missteps, especially overly broad permissions, are among the top causes of cloud breaches in SMB environments.

Using AWS Identity and Access Management (IAM), teams can enforce least-privilege access by:

• Defining role-based policies that grant only what’s needed per function. For example, a billing user shouldn’t have access to EC2 instances, and dev teams shouldn’t see production secrets.
• Disabling root account use for anything beyond initial setup. Instead, use federated identities or IAM roles with MFA.
• Eliminating long-lived credentials by rotating access keys. Use AWS IAM Identity Center (formerly AWS SSO) for session-based logins tied to the identity provider (e.g., Okta, Azure AD).

A healthcare SMB using shared admin credentials across AWS services may be compliant on paper but vulnerable in practice. Granular IAM policies, tied to monitored roles, help contain blast radius and support incident forensics if something goes wrong.

4. Require multi-factor authentication (MFA)

Even with tight IAM controls, stolen or reused credentials remain a top threat, especially in environments where small teams juggle multiple roles. That’s where multi-factor authentication (MFA) becomes critical.

MFA ensures that access requires something more than just a password. It should be non-negotiable for:

• Root users
• Admin and DevOps roles
• Any user interacting with production data or infrastructure

AWS makes implementation straightforward through virtual MFA apps (like Google Authenticator or Authy), hardware tokens, or integration with SSO platforms that support MFA enforcement.

For an SMB handling patient records or financial data, a single compromised credential without MFA could expose the entire AWS account. Enforcing MFA minimizes this risk and adds resilience against phishing, social engineering, or credential stuffing attempts.

5. Automate configurations and security controls

Once identity and access layers are secured, the next priority is eliminating manual configuration drift.

For SMBs, especially those with lean IT teams, automation isn’t just a time-saver. It’s a security multiplier. By using AWS-native tools, teams can standardize deployments, enforce guardrails, and respond to threats without delay.

Key tools and approaches include:

• AWS Config for real-time compliance checks against custom or managed security baselines, flagging issues like open ports or unencrypted volumes as they happen.
• AWS CloudFormation or Terraform to provision infrastructure in a secure, repeatable way, so dev teams don’t accidentally deploy with misconfigured security groups or public access.
• AWS Systems Manager and Lambda to automate patching, log reviews, and even auto-remediation for policy violations or failed audits.

In healthcare, for example, automation can help enforce HIPAA-aligned encryption and retention policies across resources. For fintech, it supports audit-readiness and reduces reliance on ad hoc scripts or manual checklists.

6. Monitor and audit the business environment continuously

Even well-automated environments need constant visibility. Threats evolve, workloads shift, and misconfigurations can creep in. For SMBs in sectors like healthcare and fintech, where downtime or data exposure can have legal and reputational consequences, real-time monitoring and auditing aren’t optional.

Fortunately, AWS offers integrated tools that make continuous oversight both achievable and scalable:

• Amazon GuardDuty delivers intelligent threat detection using machine learning to identify unusual patterns like port scanning, credential compromise, or data exfiltration attempts.
• AWS CloudTrail provides a detailed audit log of every API call, giving the team traceability for changes, critical for root cause analysis or compliance investigations.
• AWS Security Hub aggregates findings across AWS services, offering a unified dashboard to check alignment with frameworks like CIS Benchmarks, HIPAA, or PCI-DSS.

To stay effective, alerts must go beyond dashboards. Set up automated notifications for critical anomalies and establish ownership for reviewing, escalating, and responding to alerts. Small teams can also use third-party SIEM integrations or managed detection and response (MDR) services to extend coverage.

7. Apply patches and updates promptly

Security monitoring is only useful if it’s followed by action, and patching is one of the most critical. Unpatched systems remain one of the top causes of cloud breaches, especially when vulnerabilities are publicly known and easily exploitable.

For SMBs, falling behind on updates is often a bandwidth issue. But AWS provides tools to automate and streamline the process without disrupting operations:

• AWS Systems Manager Patch Manager allows teams to automate patching schedules for Amazon EC2 instances and on-premises hybrid environments.
• Compliance dashboards on AWS Systems Manager help track which systems are up to date and which require immediate attention.
• Maintenance windows on AWS Systems Manager can help apply patches during off-peak hours, minimizing service interruptions.

Make patching a priority for public-facing services, applications handling sensitive data, and any system tied to regulatory compliance. In healthcare and fintech, a missed patch could trigger an audit failure or data breach liability.

8. Strengthen network security controls

Once the workloads are patched and up to date, the next layer of defense is the network itself. Poorly configured network settings, like open ports or flat VPC architectures, can expose sensitive data to the internet or allow lateral movement if compromised.

To reduce the attack surface and enforce segmentation:

• Use Security Groups and Network ACLs to control inbound/outbound traffic at both the instance and subnet levels
• Replace public IPs with VPC endpoints to keep service traffic inside the AWS environment
• Deploy AWS WAF (Web Application Firewall) to block injection attacks, cross-site scripting (XSS), and other Layer 7 exploits
• Avoid open ports like 0.0.0.0/0 for SSH or RDP and use bastion hosts or Session Manager instead

For SMBs in healthcare or fintech, these network controls aren’t just good practice. They’re often required for regulatory compliance. Proactively auditing firewall rules, restricting access by IP or geography, and isolating workloads by function can significantly reduce the blast radius of any incident.

9. Encrypt sensitive data in transit and at rest

Encryption is a baseline requirement, not a bonus, especially for SMBs in healthcare or fintech where data privacy laws like HIPAA, PCI-DSS, or GLBA are non-negotiable. AWS makes encryption accessible, but it’s up to the team to configure and manage it correctly.

For data at rest, enable:

• SSE-S3 for server-side encryption in Amazon S3
• EBS encryption for volumes attached to EC2 instances
• RDS encryption for managed databases, ideally using Customer-Managed Keys (CMKs) via AWS Key Management Service (KMS)

For data in transit, always:

• Use TLS 1.2 or higher
• Manage certificates through AWS Certificate Manager (ACM) for secure HTTPS connections
• Avoid sending sensitive data over unencrypted channels, even between internal systems

Don’t stop at enabling encryption, also:

• Define key rotation schedules
• Enforce least-privilege policies for key access
• Monitor access logs for unusual activity around encryption resources

For SMBs, this ensures that even if other defenses fail, the most sensitive data remains unreadable and auditable, helping businesses stay compliant and protected at scale.

10. Invest in team training and security awareness

Technology alone doesn’t secure the cloud; people do. For SMBs, especially in high-stakes industries like healthcare and fintech, the weakest link is often user behavior, not tooling. A well-configured AWS environment can still be compromised if employees fall for phishing attempts or misconfigure permissions.

To build a security-first culture:

• Train every team member, from IT admins to frontline staff, on AWS security basics, password hygiene, MFA usage, and phishing recognition
• Utilize AWS Skill Builder learning paths or bring in certified AWS training partners like Cloudtech for hands-on workshops
• Run regular tabletop exercises and simulated incidents to test the team’s response readiness

Security awareness should be part of onboarding, reinforced during team meetings, and revisited as the environment evolves. Organizations that embed security into their day-to-day culture are not only better prepared to defend against attacks, but they also recover faster and maintain customer trust when incidents occur.

By following these practices, SMBs can build a compliant and scalable AWS environment.

‍Security maturity evolves with the business. Cloudtech helps SMBs assess their environment using AWS Security Hub benchmarks and custom KPIs such as identity sprawl, encryption coverage, and patch compliance. This allows organizations to continuously measure posture and prioritize remediation based on actual risk exposure.

2. What are the next steps after implementing MFA and IAM best practices?

‍Once foundational access controls are in place, the focus should shift to proactive threat detection and automated response. Cloudtech enables SMBs to deploy services like GuardDuty and Systems Manager Automation to detect anomalies and respond in real time, helping teams move from reactive to proactive security operations.

3. How can SMBs prevent security configurations from drifting over time?

‍Configuration drift often occurs as environments grow and change. Cloudtech mitigates this by implementing AWS Config and conformance packs that enforce predefined policies. Combined with Infrastructure as Code tools like CloudFormation, this ensures environments remain consistent, auditable, and secure at scale.

4. What should an SMB do immediately following a security incident in AWS?

‍The first priority is containment, isolating affected resources using IAM and VPC controls. Cloudtech helps SMBs build incident response playbooks that include forensic analysis with CloudTrail, root cause tracing, and automated remediation via Lambda. This shortens recovery time and helps teams close security gaps quickly.

5. Is advanced cloud security necessary if an SMB isn’t in a regulated industry?

‍Absolutely. Even without HIPAA or PCI obligations, SMBs are frequent targets due to limited defenses. Cloudtech aligns security controls to business value, not just compliance. This ensures customer data, core applications, and uptime are protected without overwhelming internal teams or over-investing in tools that don’t fit their scale.

‍

For small and mid-sized businesses (SMBs), cloud migration is an opportunity to modernize operations. However, it can also expose security blind spots if not planned carefully. Misconfigured access, exposed data, or missing compliance controls can turn a technical win into a reputational risk.

Take the case of a mid-sized healthcare provider migrating patient records to Amazon S3. The migration itself goes well, but they might overlook S3 Block Public Access by default. A week later, a routine security scan reveals that some storage buckets are publicly accessible. This puts the company at risk of violating HIPAA rules. It’s caught in time, but the instance triggers a full audit and weeks of remediation.

Incidents like this usually happen because the migration overlooks essential safeguards. This article breaks down the most common security pitfalls SMBs face during cloud migration, and shows how to avoid them with practical, preventive steps.

Key takeaways:

• Treat security as a migration stream: Security should be integrated from the planning phase through execution, not bolted on after workloads move.
• Don’t carry over legacy risks: Lift-and-shift approaches often transfer outdated controls. Always reassess configurations and patch known vulnerabilities before migration.
• IAM missteps cause the most damage: Overly permissive roles or missing MFA setups remain leading causes of breaches. Tighten access controls early.
• Compliance doesn’t auto-transfer: Moving to the cloud doesn’t automatically preserve HIPAA, PCI, or GDPR compliance. Logging, data handling, and access reviews must be revalidated.
• Small teams can win with the right tools: Cloud-native security services and automation help SMBs build strong defenses, especially when paired with expert guidance.

Key cloud migration security challenges for SMBs, and how to solve them?

Cloud migration introduces a shift in how IT environments are secured. For SMBs, this shift often happens under resource constraints, without specialized security teams or mature DevSecOps practices in place. As a result, critical vulnerabilities frequently emerge.

According to IBM’s cost of a data breach report, 40% of data breaches involved data stored across multiple environments. Breached data stored in public clouds incurred the highest average breach cost at USD 5.17 million.

Common issues like open Amazon S3 buckets, broad IAM access, insecure APIs, and unpatched workloads often stem from rushed migrations. SMBs can reduce risk by treating security as a parallel track, encrypting data, enforcing least-privilege access, automating compliance, and baking security into CI/CD pipelines. 

SMBs will face many security challenges during transition, but each of them has a fix that can be implemented early to reduce cost and downtime:

Challenge 1: Data exposure during transfer or storage

When moving data to the cloud, it’s easy to assume AWS will handle encryption by default. But during migration, especially when using tools like AWS DMS or moving large datasets to Amazon S3, data can pass through unsecured channels or land in buckets without encryption turned on. That’s when it gets risky. A misstep here could expose sensitive info like customer records, financials, or health data.

The fix: To keep data protected, encryption needs to be covered in two places: when it's moving and when it’s sitting in AWS.

For data in transit, enforce TLS 1.2 or higher.

• When using AWS DMS, turn on SSL for every connection point.
• Set bucket policies in Amazon S3 to reject unencrypted uploads.

For data at rest, turn on encryption by default.

• Use AWS KMS (Key Management Service), either AWS-managed or customer-managed keys.
• Enable encryption on Amazon S3, RDS, and EBS volumes from the start.
• Use AWS Config to alert if anything’s left unencrypted.

• Keep an eye on key usage and access patterns with AWS CloudTrail.

How one SMB handled it: A growing dental clinic group migrating its patient database to Amazon RDS ran into a pitfall. Backups weren’t encrypted, and neither were the Amazon S3 uploads coming from old file exports. However, with the help of their AWS partner, they enabled SSL connections to the Amazon RDS instance, switched on encryption using a customer-managed KMS key, and applied Amazon S3 policies to block any unencrypted objects. They also routed DMS traffic through a VPN tunnel using IPSec with AES-256.

The migration wrapped without a hitch, and passed a HIPAA audit two months later.

Challenge 2: Weak or overly permissive IAM policies

Many SMBs start out with all-hands admin access just to “get things working” during early cloud stages. But that kind of shortcut doesn’t scale. Broad IAM roles, like giving full AdministratorAccess to multiple users or using wildcard permissions (*), leave the door wide open for accidents or attacks. A single compromised user account could mean access to everything from Amazon S3 buckets to billing dashboards.

The fix: Secure IAM starts with discipline, not complexity. AWS gives the tools. SMBs just need a plan.

• Least privilege first: Define roles around job functions. For example, DevOps engineers might get full access to Amazon EC2 and AWS CloudFormation, but only read access to Amazon S3.
• Use IAM policies with explicit, scoped permissions instead of wildcards.
• Enforce MFA (Multi-Factor Authentication) for all users, especially those with console access.
• Centralize identity using AWS IAM Identity Center (formerly AWS SSO), and connect it to the existing directory (like Microsoft AD or Okta).
• Set up regular reviews using IAM Access Analyzer to catch unused permissions or over-provisioned roles.

How one SMB handled it: A fintech startup had six developers sharing a root account during testing. Fast, but dangerous. On the suggestion of their AWS partner, they split out individual IAM roles, restricted access based on team functions, and required MFA for each user. They implemented IAM Identity Center and linked it with Google Workspace for strong login control. Within a week, they went from full-access chaos to tight, auditable roles that passed their first investor security review.

Challenge 3: Misconfigured cloud environments

Default settings in AWS are designed for flexibility, not security. That’s fine when spinning up test environments, but it’s risky in production. It is easy to overlook things like open Amazon S3 buckets, 0.0.0.0/0 rules in security groups, or disabled encryption on Amazon RDS or EBS volumes. These misconfigurations leave systems exposed to the internet or unencrypted by default.

The fix: Security misconfigurations are preventable with the right guardrails in place.

• Use AWS Config to continuously scan for misaligned settings across services (e.g., unencrypted volumes, non-compliant IAM roles).
• Enable AWS Security Hub to consolidate security alerts and automatically check the environment against AWS best practices.
• Trusted Advisor provides real-time recommendations across security, performance, and cost, flagging things like publicly accessible storage or overly broad access rules.
• Establish service control policies (SCPs) in AWS Organizations to prevent high-risk configurations before they happen.
• Automate remediation with tools like AWS Systems Manager Automation or integrations with third-party platforms like Palo Alto Prisma Cloud or Datadog.

How one SMB solved it: A healthcare tech company found that one of its Amazon S3 buckets used for diagnostic image uploads was accidentally made public during testing. However, with guidance from their AWS partner, they activated Security Hub and AWS Config, which flagged the exposure. They locked down the bucket, enforced encryption at rest, and added guardrails to prevent similar issues in future environments. That quick action helped them avoid a serious HIPAA compliance violation.

Challenge 4: Unsecured APIs and integration points

During migration, existing APIs used for mobile apps, third-party integrations, or internal tools are often reused without being reassessed for cloud exposure. What was once protected behind a corporate firewall might now be reachable over the public internet. Without safeguards like authentication, rate limiting, or request validation, these endpoints become easy targets for abuse, injection attacks, or data exfiltration.

The fix: AWS offers purpose-built tools to lock down APIs without complicating development:

• Use Amazon API Gateway to serve APIs through a managed layer that supports throttling, access control, and monitoring out of the box.
• Protect public endpoints with AWS WAF (Web Application Firewall) to block common attack patterns like SQL injection or cross-site scripting.
• Enforce authentication and authorization using Amazon Cognito, custom tokens, or IAM roles for internal services.
• Log and monitor API activity with CloudWatch Logs and AWS X-Ray to detect anomalies in usage or performance.
• Use resource policies and VPC links to limit API access to only trusted networks when needed.

How one SMB solved it: A fintech startup that migrated its customer dashboard to AWS was exposing internal APIs for billing and account updates without authentication. After noticing unusual traffic patterns, their AWS partner helped deploy API Gateway in front of the services, integrated AWS WAF to filter malicious traffic, and implemented OAuth2 authentication through Cognito. These changes shut down the vulnerability and gave the team better visibility into API usage going forward.

Challenge 5: Rehosting without revisiting security posture

Many SMBs choose a lift-and-shift approach for speed, migrating workloads “as-is” to the cloud. But this often means legacy vulnerabilities make the jump too. These can include hardcoded credentials in config files, outdated OS versions, unpatched libraries, or services running with admin-level access. Once in the cloud, these overlooked issues become more dangerous due to increased exposure and scale.

The fix:
A successful rehost still needs a security checkpoint before workloads go live in AWS:

• Run pre-migration assessments to flag risky dependencies or OS-level vulnerabilities.
• Use AWS Systems Manager Patch Manager to automate patching for Amazon EC2 instances across both Linux and Windows.
• Store and rotate credentials securely using AWS Secrets Manager instead of hardcoding them in applications.
• Use Amazon Inspector to scan for known CVEs and misconfigurations as soon as the workload is in AWS.
• Apply IAM roles instead of access keys to give services temporary, scoped permissions.

How one SMB handled it: A regional HR software company rehosted its on-prem application servers to Amazon EC2 with minimal changes. Post-migration, they found hardcoded database credentials in application configs and several unpatched packages. With guidance from their AWS partner, they used AWS Inspector to identify vulnerable packages, automated OS patching via AWS Systems Manager, and moved credentials to AWS Secrets Manager. This not only improved their security posture but also passed a third-party audit required for a new enterprise client.

Challenge 6: Gaps in compliance visibility

When SMBs migrate workloads to the cloud, especially in regulated industries like healthcare or finance, compliance requirements can slip through the cracks. Teams often lose visibility into how HIPAA, PCI-DSS, or GDPR controls are being enforced in the new environment. Manual tracking gets harder across multiple accounts or regions, and missteps, like missing encryption, improper access logging, or insecure storage, can result in violations and penalties.

The fix: Maintaining compliance in AWS requires continuous monitoring, not just upfront configuration:

• Enable AWS CloudTrail to log all account activity and API calls. This creates a detailed audit trail for compliance audits.
• Use AWS Config and managed Config Rules to automatically track whether resources like Amazon S3, RDS, and IAM follow the compliance baseline (e.g., encryption enabled, public access blocked).
• Set up conformance packs for specific frameworks like HIPAA or PCI-DSS to apply a consistent set of controls across accounts.
• Use the AWS Well-Architected Tool, specifically the Security Pillar, to review workloads before and after migration for policy alignment and security gaps.

How one SMB handled it: A mid-sized healthtech company moved its appointment scheduling system to AWS. They assumed compliance would carry over, but a review showed their Amazon S3 backups lacked encryption and IAM roles had excessive permissions. Working with an AWS partner, they enabled Config Rules to enforce encryption and AWS CloudTrail for tracking changes. They also ran an Amazon Well-Architected review to close remaining gaps, helping them meet HIPAA standards before relaunch.

Challenge 7: Lack of cloud security expertise

For many SMBs, in-house IT teams are strong on traditional infrastructure but haven’t had the time or budget to go deep on cloud security. This creates blind spots during migration, especially around the shared responsibility model, IAM configuration, and native tools like CloudTrail or Security Hub. Without that context, it’s easy to miss critical setup steps or misconfigure access and logging.

The fix: Bridging the knowledge gap early helps avoid security missteps:

• Start with AWS’s free training modules on cloud security fundamentals to ground the team in core concepts.
• Use the AWS Shared Responsibility Model as a guide to define exactly what the team is responsible for versus what AWS secures.
• Involve a certified AWS Partner like Cloudtech during the planning phase. They can help design secure landing zones, set guardrails, and handle configurations that may be unfamiliar to internal teams.
• Establish a security review checkpoint for each migration phase, including planning, testing, and cutover.

How one SMB handled it: A regional payroll service moving off legacy servers wasn’t familiar with IAM best practices or how to use AWS CloudTrail. They worked with an AWS partner to define scoped roles, implement least privilege policies, and enable centralized logging across accounts. As a result, they avoided costly misconfigurations, and their internal team gained confidence by learning alongside the migration.

Challenge 8: Inconsistent security across hybrid environments

Many SMBs don’t move everything to the cloud at once. For months, or even years, they run in a hybrid model, with some systems still on-premises while others operate in AWS. The problem? Security policies often evolve separately. SMBs might have strong IAM rules and logging in AWS, but loose firewall rules or missing audit trails on-prem. That gap creates room for lateral attacks, especially if identity and access aren’t unified.

The fix: To secure hybrid environments, SMBs need to standardize their security posture across both legacy and cloud systems:

• Use AWS Organizations with Service Control Policies (SCPs) to enforce guardrails across all AWS accounts from day one.
• Deploy AWS GuardDuty for real-time threat detection and anomaly alerts across cloud workloads.
• Integrate CloudTrail logs with on-prem SIEM tools or set up AWS Security Hub to centralize findings across environments.
• For identity, consider extending Active Directory to AWS using AWS Directory Service to maintain consistent user access policies.

How one SMB handled it: A mid-sized manufacturing firm moved its CRM and analytics stack to AWS but kept its ERP on local servers. Initially, access to cloud apps required MFA, but ERP access was unchanged. After a minor breach via a compromised ERP credential, they worked with an AWS partner to align IAM, deploy GuardDuty, and use Security Hub to monitor both sides. That consistency helped shut down potential gaps, and passed their next audit without issues.

Challenge 9: DevOps speed outpacing security

For SMBs adopting DevOps, the shift to rapid releases and automated deployments is a big win. But that speed can outpace security. Developers may push code that includes hardcoded secrets, misconfigured IAM roles, or unvetted open-source libraries, often without security teams catching it until after deployment. In small teams, security reviews are sometimes skipped entirely to meet deadlines.

The fix: Security needs to be embedded early in the software delivery pipeline, not bolted on after deployment:

• Integrate static application security testing (SAST) tools like SonarQube or Amazon CodeGuru Reviewer into the CI/CD process.
• Use AWS Secrets Manager to eliminate hardcoded secrets in source code.
• Add IAM policy linting with tools like CloudFormation Guard or IAM Access Analyzer to validate roles before they're deployed.
• Apply pre-deployment scanning using Amazon Inspector for EC2 or container images.

How one SMB handled it: A SaaS startup was deploying updates twice a week, but after an incident involving an exposed API key in Git, they realized speed was coming at a cost. By embedding CodeGuru, Secrets Manager, and policy validation into their CI/CD pipelines, they caught risky changes early without slowing down releases.

Challenge 10: Cloud-to-cloud migrations without revalidation

When SMBs migrate workloads between cloud providers, or even between AWS accounts, they often assume existing security settings will carry over. But policies, encryption keys, and IAM roles don’t always translate as one might expect. This can result in missing resource-level permissions, broken encryption, or inadvertently exposed services. Something as simple as forgetting to reapply an Amazon S3 bucket policy in a new account can make private data public.

The fix: Treat every cloud-to-cloud migration as a clean slate for security. That means:

• Re-auditing all IAM roles, bucket policies, and VPC settings post-migration.
• Rotating credentials and API keys to invalidate old access paths.
• Using AWS IAM Access Analyzer and AWS Config to validate resource sharing and compliance in the new environment.
• Running automated validation scripts to confirm encryption settings (via KMS), security groups, and ACLs are correctly enforced.
• Conducting a post-migration security audit, ideally with help from a partner or AWS Well-Architected Framework review.

How one SMB handled it: A fintech SMB moved their analytics pipeline from one AWS account to another to separate environments by function. After the migration, data from an Amazon S3 bucket became accessible publicly due to a missing policy reattachment. They avoided a breach thanks to an automated Config rule that flagged the misconfiguration within minutes, but it was a close call. Post-migration auditing is now part of every internal change request.

Pro tip: Working with an AWS Partner gives SMBs access to specialized cloud security expertise that internal teams may not have. Partners can spot hidden risks early, before they lead to misconfigurations, compliance gaps, or downtime. Their experience across similar migrations helps implement preventive controls from day one, not after issues arise.

Why is cloud migration a smart move for SMBs? Key benefits explained

When small and mid-sized businesses shift from legacy IT systems to a cloud-native setup, they gain measurable reductions in operating costs and increase overall efficiency. Cloud migration eliminates the need for heavy upfront investments in hardware and maintenance, allowing organizations to align expenses with actual usage and direct resources toward growth initiatives.

A modern cloud environment also strengthens security, improves business continuity, and accelerates innovation. With the flexibility to scale on demand and enable real-time collaboration, SMBs are better equipped to adapt to changing market conditions, launch new services quickly, and support long-term business growth.

Here’s how each benefit contributes to helping SMBs operate more efficiently and scale with confidence:

1. Reducing costs and simplifying IT operations

Migrating to the cloud shifts SMBs away from costly, inflexible on-premises systems toward a usage-based operational model that directly aligns expenses with evolving business needs. Rather than investing heavily in hardware that may go underutilized or rapidly depreciate, organizations pay only for the resources they consume, making IT budgets more predictable and freeing up capital for growth initiatives.

How it helps businesses:

• Reduces CapEx and shifts to OpEx: Migrating to AWS allows businesses to replace physical servers and networking equipment with on-demand compute and storage services like Amazon EC2, Amazon S3, and AWS Lambda. This eliminates large upfront purchases and aligns expenses with usage patterns.
• Automates infrastructure management: AWS services like AWS Systems Manager, AWS OpsWorks, and AWS CloudFormation help automate patching, provisioning, configuration, and monitoring. It reduces the need for large IT teams managing infrastructure manually.
• Improves resource efficiency through right-sizing and scheduling: With tools like AWS Cost Explorer, AWS Compute Optimizer, and AWS Trusted Advisor, businesses can right-size Amazon EC2 instances, identify underused resources, and schedule workloads to run during off-peak hours, driving down costs further.

Example: Imagine a regional logistics company migrating its legacy data center to AWS. Instead of purchasing new physical servers before peak season, the company configures Amazon EC2 Auto Scaling. If demand spikes during the holidays, Auto Scaling automatically adds more compute resources, ensuring deliveries run smoothly—without paying for excess capacity during slower months. 

By using AWS Cost Explorer, the team identifies underused storage and right-sizes instances, further lowering operational expenses. Automated backups with AWS Backup ensure that if a system issue occurs, critical data is quickly restored, supporting regulatory compliance and business continuity.

Expert insight: AWS partners like Cloudtech help businesses transition their workloads to efficient event-driven, and serverless architectures, improving scalability, minimizing idle compute, and optimizing ROI. It's how SMBs achieve more with less, without compromising on performance.

2. Adaptable and future-ready IT infrastructure

Cloud platforms give SMBs the ability to adapt fast, whether it’s to support sudden growth, test new ideas, or adjust to changing market dynamics. Instead of being locked into fixed infrastructure, businesses can scale services in or out on demand and move with agility in how they build and deploy applications.

How it helps businesses:

• Manages unpredictable demand with elasticity: Services like AWS Auto Scaling, AWS Elastic Load Balancing, and Amazon CloudFront allow businesses to automatically respond to traffic surges or drops, ensuring performance without waste.
• Accelerates delivery cycles: With AWS Lambda, AWS Fargate, and Amazon EKS, businesses can build and release new features faster using microservices and serverless architectures, cutting down deployment times and enabling experimentation.
• Supports business pivots without friction: Whether entering new markets or updating offerings, cloud-native tools adapt easily to evolving goals, enabling rapid changes without lengthy infrastructure projects.

Example: Suppose an e-commerce company faces a surge in online traffic during a major sales event. With AWS Auto Scaling, their application servers automatically spin up new Amazon EC2 instances in response, ensuring website performance remains steady for every customer, even as demand rapidly triples. At the same time, Amazon CloudFront caches product images and pages at edge locations, reducing latency and workload on origin servers for shoppers nationwide. After the sale, the infrastructure scales back down, so costs stay in line with actual usage, all without manual intervention.

Pro tip: Cloudtech’s application modernization service can help SMBs design modular, event-driven applications that scale automatically and deploy fast. With serverless and container-based architectures, businesses can move nimbly, capitalize on new opportunities, and keep infrastructure spending efficient as needs evolve.

3. Built-in security and operational continuity

Downtime, data breaches, and compliance lapses don’t just hurt SMBs, they can derail growth entirely. Cloud-native architectures provide built-in resilience, strong security measures, and recovery mechanisms that keep the business protected and operational, even when things go wrong.

How it helps businesses:

• Minimizes disruptions through redundancy: Multi-AZ (Availability Zone) and cross-region deployments ensure the data and workloads are always accessible, even if one zone experiences failure.
• Enables rapid recovery with automation: Services like AWS Backup, AWS CloudWatch, and AWS CloudTrail offer automated backup, monitoring, and alerting. This allows businesses to detect anomalies in real-time and recover faster from outages or incidents.
• Secures data end-to-end: Native tools like AWS Key Management Service (KMS), AWS Identity and Access Management (IAM), and Amazon GuardDuty help encrypt data, control access, and continuously monitor for threats or unusual behavior, ensuring regulatory compliance and peace of mind.

Example: Consider a healthcare provider moving operations to AWS in order to comply with HIPAA regulations. By activating versioning in Amazon S3 and scheduling automated backups through AWS Backup, the organization secures patient data with less manual oversight. If a local IT issue disrupts onsite files, staff can restore critical records from AWS in minutes, avoiding data loss and maintaining compliance. Continuous monitoring with AWS CloudWatch also helps identify any misconfigured permissions early, allowing the team to resolve vulnerabilities before they become a security threat.

Pro tip: Cloudtech can help SMBs design AWS environments that are not just secure, but audit-ready. From implementing automated backup strategies to setting up proactive monitoring and threat detection, Cloudtech ensures businesses stay resilient without sacrificing speed or scalability.

4. Future-ready technology for growing businesses

One of the most powerful benefits of cloud platforms for SMBs is on-demand access to cutting-edge technology, without the overhead of managing or building it from scratch. From AI and machine learning to real-time analytics and serverless computing, cloud-native services help businesses modernize operations, personalize customer experiences, and innovate faster than ever before.

How it helps businesses:

• Accelerates innovation cycles: Services like AWS Amplify and Amazon Bedrock enable rapid prototyping and deployment using low-code/no-code frameworks, meaning SMBs can build applications quickly with minimal coding by using visual tools and pre-built components, accelerating time to market.
• Enables experimentation without risk: Tools like Amazon SageMaker for ML modeling and Amazon QuickSight for business intelligence let teams test ideas, analyze trends, and build data-driven products, without setting up infrastructure or managing data pipelines.
• Lowers the barrier to entry for emerging tech: Cloud-native services abstract away the complexity of managing compute, storage, and networking, allowing SMBs to use AI, NLP, and automation tools without a dedicated R&D team.

Example: Suppose a digital marketing agency wants to improve how it delivers value to its clients. By using Amazon Comprehend, the agency can instantly analyze thousands of customer reviews and campaign interactions, extracting real-time sentiment insights without building a complex NLP system. These analytics are integrated into campaign strategies, cutting optimization timelines in half and increasing both engagement and client retention, all without hiring in-house data scientists.

Pro tip: Collaboration works best when data and apps are exactly where teams need them, secure, centralized, and always accessible. AWS partners like Cloudtech can help SMBs build this foundation with cloud-native workspaces, real-time document management, and GenAI-ready data prep services. 

6. Sustainable growth and profitability

Cloud platforms are about building leaner, smarter operations. For SMBs, that means using tools like autoscaling, serverless functions, and intelligent storage tiers to eliminate waste, control costs, and act on data in real time. Architecting with efficiency in mind, using containerization, infrastructure as code, and usage-based pricing models. This helps reduce both environmental impact and cloud spend, all without sacrificing speed or flexibility.

How it helps businesses:

• Drives lean, cost-effective operations: Cloud services remove the need for idle hardware and oversized capacity. With pay-as-you-go pricing and auto-scaling, businesses use only what they need, and scale up when growth demands it.
• Enables smarter planning and execution: With advanced analytics tools like Amazon Redshift and AWS Glue, businesses can predict trends, forecast demand, and respond in near real time.
• Promotes greener choices by design: Migrating to energy-efficient infrastructure in the cloud reduces emissions, especially when compared to maintaining traditional on-premises servers.

Example: Imagine a sustainable apparel company seeking to improve margins while reducing waste. By consolidating inventory and customer insights in Amazon Redshift, the company quickly identifies which products sell fastest and which lag behind. If slow-moving items are promptly discontinued, inventory waste drops significantly. Instead of overstocking, the business maintains leaner shelves, resulting in a 25% reduction in waste and an increase in profitability per product line, all while supporting its long-term sustainability goals.

Pro tip: Growth shouldn’t come at the cost of efficiency, or the environment. Cloudtech helps SMBs architect lean, future-ready systems by combining serverless infrastructure, automated analytics, and GenAI-ready data prep.

Cloud migration offers SMBs a clear path to modernizing outdated infrastructure, improving performance, and scaling with demand. But while the benefits are well understood, the true costs are often underestimated. From unplanned downtime to underused services and post-migration inefficiencies, these hidden costs can erode ROI if not addressed early.

This guide breaks down the key cost drivers SMBs should anticipate during a cloud migration, and how AWS-native tools can help monitor and control spending.

Key takeaways:

• Without upfront planning, SMBs may face unexpected charges from overprovisioned resources, idle services, or unoptimized storage tiers.
• Using tools like AWS Compute Optimizer and TCO Calculator helps align compute and storage to real-world workloads before migration begins.
• Unplanned egress fees, legacy license constraints, and poorly planned cutovers can significantly raise migration expenses.
• Clear tagging, budget alerts, and cost tracking with AWS Budgets and Cost Explorer help prevent cost sprawl and maintain visibility across teams.
• Cloudtech combines technical precision with SMB-focused strategy to help businesses migrate smarter, avoiding common pitfalls and unlocking long-term cloud value.

What’s driving up cloud migration costs? 10 hidden risks and how to fix them

More than just a lift-and-shift operation, cloud migration is a transformation of how data, compute, and applications are managed. For SMBs, overlooking cost drivers like overprovisioned instances, idle storage, or underused managed services can quickly undermine the value of the migration. These accumulate over months in the form of inflated AWS bills, unpredictable budget spikes, and underperforming workloads.

For example, an SMB that migrates its database workloads to Amazon RDS without optimizing instance size or enabling storage auto-scaling may end up paying for capacity it never uses, while also experiencing performance issues under peak load. 

SMBs can avoid surprises, preserve ROI, and ensure their cloud environments remain cost-effective and performant by identifying and mitigating such hidden costs early:

1. Overprovisioned compute resources

One of the most overlooked expenses during cloud migration is the cost of oversized compute instances. Many SMBs, aiming to avoid performance issues, default to Amazon EC2 instance types that far exceed their actual needs. They provision m5.2xlarge or c6i.large when a t3.medium or even a AWS Lambda-based architecture might suffice. These decisions are often made without baseline metrics, leading to unused CPU, underutilized memory, and inflated hourly billing.

How to fix it: SMBs should take a measurement-based approach before and after migration:

• Use AWS Application Discovery Service to collect actual utilization data from on-prem workloads over time.
• Use AWS Compute Optimizer to analyze usage patterns and recommend cost-efficient EC2 instance types based on actual CPU, memory, and I/O metrics.
• Configure Auto Scaling Groups with performance-based policies, and replace always-on instances with AWS Lambda or Fargate for intermittent workloads.
• Use the AWS Pricing Calculator and TCO Calculator to compare instance types, Savings Plans, and Reserved Instances.

Pro tip: AWS partners like Cloudtech support SMBs by conducting a detailed workload assessment and sizing exercise before migration. They also configure environment-wide tagging and automation scripts to detect and decommission underused resources post-migration, so excess spend doesn’t go unnoticed over time.

2. Data transfer and egress fees

While data storage in AWS (like S3 or RDS) is relatively predictable, data movement costs are often overlooked, especially when large volumes are transferred between services, across regions, or out of AWS entirely.

Two key cost drivers for SMBs:

• Inter-AZ and inter-region transfers: Moving data between Availability Zones (AZs) or AWS Regions (e.g., from us-east-1 to us-west-2) incurs per-GB charges, even within the same account.
• Data egress to the internet: Transferring data out of AWS (e.g., downloading from an Amazon S3 bucket or exposing APIs to external clients) is billed by GB, with no free tier after the first 100 GB/month.

For example, if a healthcare SMB regularly moves EHR backup files between regions for compliance without using regional services effectively, it may be incurring thousands per year in silent inter-region transfer fees.

How to fix it: SMBs can mitigate these costs with careful architecture and AWS-native controls:

• Wherever possible, keep compute and storage services in the same region and AZ. Use Availability Zone Affinity for EC2 placement to reduce intra-AZ traffic.
• For Amazon S3, DynamoDB, and other services, route traffic through VPC endpoints to avoid NAT gateway or internet transit charges.
• Distribute content using Amazon CloudFront, reducing origin fetches and external bandwidth usage.
• Set up AWS Cost Explorer with usage type filtering (DataTransfer-Out-Bytes) and create AWS Budgets alerts to catch spikes early.

Pro tip: For SMBs with regular cross-region replication or large outbound traffic (e.g., B2B data sharing, backups, public file downloads), Cloudtech can restructure the architecture using services like Amazon S3 Replication with intelligent lifecycle policies, AWS Global Accelerator, and private interconnects.

3. Storage sprawl

As SMBs migrate data to the cloud, storage usage often grows unchecked across services like Amazon S3, EBS, EFS, and RDS snapshots. Files are duplicated for testing, backups are retained longer than necessary, and old volumes are left orphaned. 

This uncontrolled growth, known as storage sprawl, leads to ballooning monthly bills, especially when data sits in higher-cost storage tiers like S3 Standard or unused provisioned EBS volumes.

Common scenarios include:

• Development teams taking frequent snapshots of RDS or EBS volumes and forgetting to delete them.
• Large media or log files accumulating in S3 buckets without lifecycle policies.
• Test environments being spun up with duplicated datasets, then left running indefinitely.

Even storing 10 TB of unnecessary Amazon S3 data in Standard storage instead of S3 Glacier or S3 Intelligent-Tiering can add thousands in annual spend, with no business value returned.

How to fix it: Avoiding storage sprawl requires visibility, automation, and lifecycle enforcement:

• Automatically transition infrequently accessed data to more cost-effective storage classes (e.g., S3 Intelligent-Tiering, S3 Glacier, or S3 Glacier Deep Archive) and delete expired objects.
• Use Amazon Data Lifecycle Manager to automate snapshot creation and retention policies for volumes and AMIs.
• Use AWS Trusted Advisor or Compute Optimizer to identify unattached EBS volumes and idle EFS instances.
• Enable AWS Cost Explorer, filtered by usage type (TimedStorage-Snapshot, TimedStorage-ByteHrs) to catch spikes in unused or high-cost storage classes.

4. Idle resources post-migration

After migrating to the cloud, it’s common for SMBs to leave unused or underutilized resources running, especially temporary workloads spun up for testing or transitional services that are no longer needed. These “zombie resources” continue to generate monthly costs without delivering business value.

Examples include:

• EC2 instances left running with no traffic or CPU usage.
• EBS volumes detached from instances but still accruing storage charges.
• RDS instances provisioned for staging environments and forgotten after go-live.
• Load balancers, NAT gateways, or Elastic IPs idle but still metered by the hour.

Even a few idle t3.medium EC2 instances, unmonitored NAT gateways, or unused RDS databases can lead to hundreds or thousands of dollars per month in waste, especially for SMBs operating under tight budgets or cost constraints.

How to fix it: Post-migration optimization is essential to avoid long-term inefficiencies:

• Create alarms for low CPU/network utilization on Amazon EC2, Amazon RDS, or AWS Lambda functions.
• Implement resource tagging (e.g., env:dev, owner:team) and use AWS Resource Groups or AWS Config Rules to detect unused assets.
• Continuously scan for underutilized or idle resources across EC2, EBS, ELB, and RDS.
• Use Instance Scheduler on AWS to stop dev/test workloads outside business hours.
• Use AWS Cost Explorer and Detailed Billing Reports (DBR) to identify persistent charges from low-activity resources.

Pro tip: For SMB clients, Cloudtech deploys automated tagging frameworks and idle resource cleanup scripts using AWS Lambda and EventBridge, along with weekly CloudWatch utilization reports.

5. License-related costs during rehosting

When SMBs migrate existing applications to AWS without rearchitecting (a lift-and-shift or rehosting strategy), they often carry over existing commercial licenses for databases, operating systems, or middleware without considering how cloud billing models differ from on-prem.

Two common issues emerge:

• SMBs using Microsoft SQL Server, Windows Server, or Oracle under on-prem licensing may discover that these licenses don’t fully transfer to AWS EC2 or RDS environments, or require strict license mobility conditions.
• If SMBs spin up EC2 instances with pre-installed licensed AMIs (e.g., Windows + SQL), but also pay for existing licenses separately, they end up paying twice, once to AWS and once to their legacy provider.

For example, rehosting a SQL Server workload to Amazon EC2 without checking the license mobility rights may force SMBs into paying AWS license-included pricing and their existing vendor’s fees, resulting in significant unexpected monthly costs.

How to fix it:

• Use AWS License Manager and AWS Systems Manager Inventory to track all software licenses, editions, and terms prior to rehosting.
• For workloads where BYOL isn’t viable, opt for AWS license-included EC2 AMIs to avoid vendor audits and compliance issues.
• Before rehosting Microsoft or Oracle products, confirm terms with vendors. AWS offers Dedicated Hosts or License Manager options to support compliant BYOL.
• Configure AWS Config rules or License Manager policies to prevent unauthorized deployments of licensed software.

Pro tip: For SMBs running commercial databases or licensed software, Cloudtech maps each workload to the most cost-effective AWS hosting model, whether that’s Amazon RDS with license-included pricing, Amazon EC2 with BYOL, or containerization to eliminate licenses entirely. 

6. Downtime during cutover

One of the most underestimated costs of cloud migration is business disruption during the final cutover, the moment when traffic and operations switch from legacy systems to the cloud. Even a few hours of downtime can impact SMBs significantly, leading to:

• Lost revenue from unavailable customer-facing services (e.g., appointment booking platforms, payment systems).
• Operational delays due to inaccessible internal systems like ERPs or CRMs.
• Data inconsistency if records are modified during an uncoordinated switchover window.

For example, a healthcare SMB migrating its EHR system without a robust cutover plan could risk incomplete patient data syncing, impacting care continuity or compliance with HIPAA access controls.

How to fix it: Avoiding downtime during cutover requires incremental, tested transition strategies using AWS-native tools:

• Replicate source servers in near real-time and run cutover rehearsals to validate performance, authentication, and connectivity before flipping the switch.
• Create duplicate environments with Route 53 traffic shifting or Elastic Load Balancer listeners to allow seamless switchover without DNS propagation delays.
• Use AWS Systems Manager Automation to orchestrate cutover workflows, ensuring tasks like final syncs, DNS updates, and user notifications are executed in the right order.
• Run both legacy and cloud systems temporarily with sync tools like AWS DMS (for databases) or AWS DataSync (for file systems) to confirm functional parity before full transition.

7. Underutilized managed services

AWS offers a wide array of managed services like Amazon RDS, Amazon OpenSearch Service, AWS Glue, and Amazon MQ, which promise scalability and reduced operational overhead. However, many SMBs adopt these services without fully using their capabilities, resulting in recurring charges for features or capacity that aren’t aligned with actual usage.

Common examples include:

• Running multi-AZ RDS instances for dev/test databases that don’t require high availability.
• Launching Amazon EMR or Glue jobs on a schedule, even when no data needs processing.
• Using Amazon OpenSearch with high IOPS EBS volumes and multiple nodes for low-volume logs.
• Leaving Elastic Load Balancers (ELBs) active in environments with minimal traffic.

Because these services are billed by provisioned resources (not always by usage), idle or oversized configurations can add thousands annually in waste, especially for SMBs who assume “managed” means “optimized.”

How to fix it: Avoiding this trap requires performance tuning and usage-based configuration, using the following AWS tools and techniques:

• For services like Amazon RDS and AWS DynamoDB, enable Auto Scaling or switch to Amazon Aurora Serverless v2, which adjusts capacity on-demand.
• Use AWS CloudWatch to track query volume, CPU utilization, and memory pressure. Based on thresholds, pause or resize underused services (e.g., using RDS stop/start features).
• Use AWS Compute Optimizer for RDS and Cost Explorer’s utilization reports to identify overprovisioned tiers.
• Instead of running separate managed services per team or app, consolidate into shared resources with access controls (e.g., a central Glue job triggered by EventBridge for multiple apps).
• Use AWS Resource Groups, tagging (env, team, owner), and Config Rules to auto-detect managed services with persistent underutilization.

Pro tip: Cloudtech performs periodic reviews of managed workloads, helping SMBs switch to serverless variants (like Aurora Serverless or Amazon Athena), and deploy usage-based triggers that automatically pause or scale services. 

8. Training and ramp-up time for teams

After migration, SMBs often find that internal teams aren’t fully prepared to operate or manage the new cloud environment. Unlike on-prem infrastructure, AWS introduces new concepts like auto-scaling groups, IAM roles, serverless workflows, usage-based billing, and managed services.

Without prior enablement:

• Developers may misconfigure services like Amazon S3 or AWS Lambda, leading to performance bottlenecks or security gaps.
• Ops teams may struggle with log aggregation, monitoring setups (e.g., CloudWatch, CloudTrail), or automated deployments.
• Finance teams may misinterpret usage-based billing reports, resulting in confusion over cost spikes or chargebacks.

This lack of cloud fluency not only slows down adoption but also introduces risks of misconfiguration, non-compliance, and inefficient use of resources.

How to fix it: Cloud training should be role-specific, continuous, and closely tied to the workloads being migrated:

• Enroll teams in curated learning paths such as “Cloud Essentials for SMBs,” “Operations in AWS,” or “Serverless App Development.” Many of these are free and designed for non-enterprise audiences.
• Set up isolated AWS accounts or Control Tower organizational units (OUs) with budget alerts so teams can experiment safely without financial or production risk.
• Create scoped IAM roles (e.g., read-only access, billing viewer, or dev sandbox admin) to let teams explore while maintaining security boundaries.
• Align enablement with current or upcoming cloud features in the roadmap—e.g., train on Step Functions before rolling out a serverless pipeline.
• Help finance and operations teams become fluent in tracking performance and spend from day one.

Pro tip: Cloudtech embeds enablement into every phase of the migration process, not as an afterthought. They deliver tailored onboarding plans that include access to AWS Skill Builder, deploy real-use sandbox environments with scoped permissions, and conduct team-specific sessions on tools like AWS CloudFormation, Amazon CloudWatch, and AWS Cost Explorer. 

9. Security misconfigurations post-migration

Post-migration, many SMBs assume that once data and workloads are live in AWS, security is automatically handled. But cloud security operates under a shared responsibility model, and SMBs should not overlook their side of the equation.

Common security misconfigurations include:

• Public Amazon S3 buckets unintentionally exposing sensitive files.
• Overly permissive IAM roles granting broad access across resources.
• Disabled logging on critical services like Amazon RDS, Amazon EC2, or VPC flow logs.
• Unencrypted data at rest or in transit, violating compliance standards like HIPAA or SOC 2.
• Open ports or misconfigured security groups exposing workloads to the public internet.

These missteps can lead to data breaches, failed audits, and reputational damage, especially for SMBs handling regulated data like personal health information (PHI) or payment records.

How to fix it: AWS provides built-in tools and frameworks to enforce security policies proactively:

• Tools like AWS Config and AWS Security Hub continuously evaluate resources against best practices and compliance baselines (e.g., CIS AWS Foundations Benchmark, HIPAA, PCI).
• Ensure activity tracking is active across all regions with AWS CloudTrail and AWS CloudWatch Logs. Use log filtering to detect anomalies in authentication or API access.
• Identify resources (like roles or S3 buckets) shared externally or misconfigured with broad access using IAM Access Analyzer.
• Use AWS KMS for key management and enforce encryption on Amazon S3, EBS, and RDS by default.
• Use VPC security group rules, Network ACLs, and AWS Firewall Manager to control and audit network access.

Pro tip: Cloudtech enforces AWS security best practices during and after migration. It pre-configures guardrails such as encryption policies, IAM role boundaries, and AWS Config compliance packs tailored to SMB environments. 

10. Unclear post-migration ownership and billing accountability

After cloud migration, SMBs often face internal confusion over who owns what — both technically and financially. Unlike traditional on-prem systems where infrastructure is centrally managed, cloud workloads can span multiple AWS accounts, projects, or business units. Without defined ownership:

• Teams may unknowingly spin up redundant resources, leading to unexpected charges.
• Cost anomalies go unnoticed because no one is actively monitoring usage.
• Support incidents or access requests are delayed due to unclear administrative responsibility.
• Finance teams struggle to reconcile cloud invoices with internal budgets or departments.

This lack of clarity leads to wasted spend, security risks, and friction between technical and business units.

How to fix it: Fixing this requires a governance model built around clear tagging, budgeting, and ownership practices:

• Create a multi-account structure where each workload or department has a separate account with scoped access and budget enforcement.
• Assign spend limits to teams or workloads using AWS Budgets and Budget Alerts. Send alerts if actuals or forecasts exceed thresholds.
• Use mandatory cost allocation tags (owner, env, cost-center) and enforce them with AWS Tag Policies so every resource is traceable.
• Enable granular cost analysis by project, environment, or team with AWS Cost Explorer. Use Resource Groups to group costs logically.
• Assign ownership of each workload (both technical and financial) and conduct monthly reviews using AWS reports (e.g., CUR - Cost and Usage Reports).

Pro tip: Partnering with an experienced AWS provider early in the migration process helps SMBs avoid missteps that lead to long-term cost creep. From right-sizing compute to enforcing security and billing policies, certified partners like Cloudtech ensure every phase is optimized.
