Businesses are increasingly adopting AWS Lambda to automate processes, reduce operational overhead, and respond to changing customer demands. As businesses build and scale their applications, they are likely to encounter specific AWS Lambda limits related to compute, storage, concurrency, and networking.
Each of these limits plays a role in shaping function design, performance, and cost. For businesses, including small and medium-sized (SMBs), understanding where these boundaries lie is important for maintaining application reliability. Knowing how to operate within them helps control expenses effectively.
This guide will cover the most relevant AWS Lambda limits for businesses and provide practical strategies for monitoring and managing them effectively.
Key Takeaways
- Hard and soft limits shape every Lambda deployment: Memory (up to 10,240 MB), execution time (15 minutes), deployment package size (250 MB unzipped), and a five-layer cap are non-negotiable. Concurrency and storage quotas can be increased for growing workloads.
- Cost control and performance depend on right-sizing: Adjusting memory, setting timeouts, and reducing package size directly impact both spend and speed. Tools like AWS Lambda Power Tuning and CloudWatch metrics help small and medium businesses stay on top of usage and avoid surprise charges.
- Concurrency and scaling must be managed proactively: Reserved and provisioned concurrency protect critical functions from throttling, while monitoring and alarms prevent bottlenecks as demand fluctuates.
- Deployment and storage strategies matter: Use AWS Lambda Layers to modularize dependencies, Amazon Elastic Container Registry for large images, and keep /tmp usage in check to avoid runtime failures.
- Cloudtech brings expert support: Businesses can partner with Cloudtech to streamline data pipelines, address compliance, and build scalable, secure solutions on AWS Lambda, removing guesswork from serverless adoption.
What is AWS Lambda?
AWS Lambda is a serverless compute service that allows developers to run code without provisioning or managing servers. The service handles all infrastructure management tasks, including server provisioning, scaling, patching, and availability, enabling developers to focus solely on writing application code.
AWS Lambda functions execute in a secure and isolated environment, automatically scaling to handle demand without requiring manual intervention.
As an event-driven Function as a Service (FaaS) platform, AWS Lambda executes code in response to triggers from various AWS services or external sources. Each AWS Lambda function runs in its own container.
When a function is created, AWS Lambda packages it into a new container and executes it on a multi-tenant cluster of machines managed by AWS. The service is fully managed, meaning customers do not need to worry about updating underlying machines or avoiding network contention.
Why use AWS Lambda, and how does it help?
For businesses, AWS Lambda is designed to address the challenges of building modern applications without the burden of managing servers or complex infrastructure.
It delivers the flexibility to scale quickly, adapt to changing workloads, and integrate smoothly with other AWS services, all while keeping costs predictable and manageable.
- Developer agility and operational efficiency: By handling infrastructure, AWS Lambda lets developers focus on coding and innovation. Its auto-scaling supports fluctuating demand, reducing time-to-market and operational overhead.
- Cost efficiency and financial optimization: AWS Lambda charges only for compute time used, nothing when idle. With a free tier and no upfront costs, many small businesses report savings of up to 85%.
- Built-in security and reliability: AWS Lambda provides high availability and fault tolerance, and integrates with AWS IAM for custom access control. Security is managed automatically, including encryption and network isolation.
AWS Lambda offers powerful advantages, but like any service, it comes with specific constraints to consider when designing your applications.
What are AWS Lambda limits?
AWS Lambda implements various limits to ensure service availability, prevent accidental overuse, and ensure fair resource allocation among customers. These limits fall into two main categories: hard limits, which cannot be changed, and soft limits (also referred to as quotas), which can be adjusted through AWS Support requests.
1. Compute and storage limits
When planning business workloads, it’s useful to know the compute and storage limits that apply to AWS Lambda functions.
Memory allocation and central processing unit (CPU) power
AWS Lambda allows memory allocation ranging from 128 megabytes (MB) to 10,240 MB in 1-MB increments. The memory allocation directly affects CPU power, as AWS Lambda allocates CPU resources proportionally to the memory assigned to the function. This means higher memory settings can improve execution speed for CPU-intensive tasks, making memory tuning a critical optimization strategy.
Maximum execution timeout
AWS Lambda functions have a maximum execution time of 15 minutes (900 seconds) per invocation. This hard limit applies to both synchronous and asynchronous invocations and cannot be increased.
Functions that require longer processing times should be designed using AWS Step Functions to orchestrate multiple AWS Lambda functions in sequence.
Deployment package size limits
The service imposes several deployment package size restrictions:
- 50 MB zipped for direct uploads through the AWS Lambda API or Software Development Kits (SDKs).
- 250 MB unzipped for the maximum size of deployment package contents, including layers and custom runtimes.
- A maximum uncompressed image size of 10 gigabytes (GB) for container images, including all layers.
Temporary storage limitations
Each AWS Lambda function receives 512 MB of ephemeral storage in the /tmp directory by default. This storage can be configured up to 10 GB for functions requiring additional temporary space. The /tmp directory provides fast Input/Output (I/O) throughput compared to network file systems and can be reused across multiple invocations for the same function instance. The container image must be hosted in Amazon Elastic Container Registry (ECR). This reuse depends on the function instance being warm, and shouldn’t be relied upon for persistent data.
Code storage per region
AWS provides a default quota of 75 GB for the total storage of all deployment packages that can be uploaded per region. This soft limit can be increased to terabytes through AWS Support requests.
2. Concurrency limits and scaling behavior
Managing how AWS Lambda functions scale is important for maintaining performance and reliability, especially as demand fluctuates.
Default concurrency limits
By default, AWS Lambda provides accounts with a total concurrency limit of 1,000 concurrent executions per region (can be increased via support) across all functions in an AWS Region. This limit is shared among all functions in the account, meaning that one function consuming significant concurrency can affect the ability of other functions to scale.
Concurrency scaling rate
AWS Lambda implements a concurrency scaling rate of 1,000 execution environment instances every 10 seconds (equivalent to 10,000 requests per second every 10 seconds) for each function.
This rate limit protects against over-scaling in response to sudden traffic bursts while ensuring most use cases can scale appropriately. The scaling rate is applied per function, allowing each function to scale independently.
Reserved and provisioned concurrency
AWS Lambda offers two concurrency control mechanisms:
Reserved concurrency sets both the maximum and minimum number of concurrent instances that can be allocated to a specific function. When a function has reserved concurrency, no other function can use that concurrency.
This ensures critical functions always have sufficient capacity while preventing downstream resource overwhelm. Configuring reserved concurrency incurs no additional charges.
- Provisioned concurrency pre-initializes a specified number of execution environments to respond immediately to incoming requests. This helps reduce cold start latency and can achieve consistent response times, often in double-digit milliseconds, especially for latency-sensitive applications. However, provisioned concurrency incurs additional charges.
3. Network and infrastructure limits
Network and infrastructure limits often set the pace for reliable connectivity and smooth scaling.
Elastic network interface (ENI) limits in virtual private clouds (VPCs)
AWS Lambda functions configured to run inside a VPC create ENIs to connect securely. The number of ENIs required depends on concurrency, memory size, and runtime characteristics. The default ENI quota per VPC is 500 and is shared across AWS services.
API request rate limits
AWS Lambda imposes several API request rate limits:
- GetFunction API requests: 100 requests per second (cannot be increased).
- GetPolicy API requests: 15 requests per second (cannot be increased).
- Other control plane API requests: 15 requests per second across all APIs (cannot be increased).
For invocation requests, each execution environment instance can serve up to 10 requests per second for synchronous invocations, while asynchronous invocations have no per-instance limit.
AWS Lambda has several built-in limits that affect how functions run and scale. These limits fall into different categories, each shaping how you design and operate your workloads.
The common types of AWS Lambda limits
AWS Lambda enforces limits to ensure stability and fair usage across all customers. These limits fall into two main categories, each with its own impact on how functions are designed and managed:
Hard limits
Hard limits represent fixed maximums that cannot be changed regardless of business requirements. These limits are implemented to protect the AWS Lambda service infrastructure and ensure consistent performance across all users. Key hard limits include:
- Maximum execution timeout of 15 minutes.
- Maximum memory allocation of 10,240 MB.
- Maximum deployment package size of 250 MB (unzipped).
- Maximum container image size of 10 GB.
- Function layer limit of five layers per function. Each AWS Lambda layer can be up to 50 MB when compressed, and up to 5 layers can be used per function.
These limits require architectural considerations and cannot be circumvented through support requests.
Soft limits (Service quotas)
Soft limits, also referred to as service quotas, represent default values that can be increased by submitting requests to AWS Support. These quotas are designed to prevent accidental overuse while allowing legitimate scaling needs. Primary soft limits include:
- Concurrent executions (default: 1,000 per region).
- Storage for functions and layers (default: 75 GB per region).
- Elastic Network Interfaces per VPC (default: 500).
Businesses can request quota increases through the AWS Service Quotas dashboard or by contacting AWS Support directly. Partners like Cloudtech can help streamline this process, offering guidance on quota management and ensuring your requests align with best practices as your workloads grow.
How to monitor and manage AWS Lambda limitations?
Effective limit management requires proactive monitoring and strategic planning to ensure optimal function performance and cost efficiency.
1. Monitoring limits and usage
Staying on top of AWS Lambda limits requires more than just setting up functions; it calls for continuous visibility into how close workloads are to hitting important thresholds. The following tools and metrics enable organizations to track usage patterns and respond promptly if limits are approached or exceeded.
- Use the AWS Service Quotas Dashboard: Track current limits and usage across all AWS services in one place. You’ll see both default values and your custom quotas, helping you spot when you’re nearing a threshold.
- Monitor AWS Lambda with Amazon CloudWatch: This automatically captures AWS Lambda metrics. Set up alerts for:
- ConcurrentExecutions: Shows how many functions are running at once.
- Throttles: Alerts you when a function is blocked due to hitting concurrency limits.
- Errors and DLQ (Dead Letter Queue) Errors: Helps diagnose failures.
- Duration: Monitors how long your functions are running.
2, Managing concurrency effectively
Effectively managing concurrency is important for both performance and cost control when running workloads on AWS Lambda.
- Reserved Concurrency: Guarantees execution capacity for critical functions and prevents them from consuming shared pool limits. Use this for:
- High-priority, always-on tasks
- Functions that others shouldn't impact
- Systems that talk to limited downstream services (e.g., databases)
- Provisioned Concurrency: Keeps pre-warmed instances ready, no cold starts. This is ideal for:
- Web/mobile apps needing instant response
- Customer-facing APIs
- Interactive or real-time features
- Requesting limit Increases: If you're expecting growth, request concurrency increases via the AWS Service Quotas console. This includes:
- Traffic forecasts
- Peak load expectations (e.g., holiday traffic)
- Known limits of connected systems (e.g., database caps)
3. Handling deployment package and storage limits
Managing deployment size and storage is important for maintaining the efficiency and reliability of AWS Lambda functions. The following approaches demonstrate how organizations can operate within these constraints while maintaining flexibility and performance.
- Use Lambda Layers: Avoid bloating each function with duplicate code or libraries. These layers help teams:
- Share dependencies across functions
- Keep deployment sizes small
- Update shared code from one place
- Stay modular and maintainable
Limits: 5 layers per function. The total unzipped size (including function and layers) must be ≤ 250 MB.
- Use Amazon ECR for large functions: For bigger deployments, use container images via Amazon ECR. These benefits include:
- Package up to 10 GB of images
- Support any language or framework
- Simplify dependency management
- Enable automated image scanning for security.
4. Manage temporary storage (/tmp)
Each function receives 512 MB of ephemeral storage by default (which can be increased to 10 GB). The best practice is to:
- Clean up temp files before the function exits
- Monitor usage when working with large files
- Stream data instead of storing large chunks
- Request more ephemeral space if needed
5. Dealing with execution time and memory limits
Balancing execution time and memory allocation is crucial for both performance and cost efficiency in AWS Lambda. The following strategies outline how businesses can optimize code and manage complex workflows to stay within these limits while maintaining reliable operations.
- Optimize for performance and cost
- Use AWS X-Ray and CloudWatch Logs to profile slow code
- Minimize unused libraries to improve cold start time
- Adjust memory upwards to gain CPU power and reduce runtime
- Use connection pooling when talking to databases
- Break complex tasks into smaller steps: For functions that can’t finish within 15 minutes, use AWS Step Functions to:
- Chain multiple functions together
- Run steps in sequence or parallel
- Add retry and error handling automatically
- Maintain state between steps
How does AWS Lambda help SMBs?
Businesses can use AWS Lambda to address a wide range of operational and technical challenges without the overhead of managing servers. However, SMBs find this needful for agile, cost-effective solutions that scale with their growth, without the burden of managing servers or complex infrastructure.
The following examples highlight how AWS Lambda supports core SMB needs, from providing customer-facing applications to automating internal processes.
- Web and mobile backends: AWS Lambda enables the creation of scalable, event-driven Application Programming Interfaces (APIs) and backends that respond almost in real-time to customer activity. The service can handle sophisticated features like authentication, geo-hashing, and real-time messaging while maintaining strong security and automatically scaling based on demand. SMBs can launch responsive digital products without investing in complex backend infrastructure or dedicated teams.
- Real-time data processing: The service natively integrates with both AWS and third-party real-time data sources, enabling the instant processing of continuous data streams. Common applications include processing data from Internet of Things (IoT) devices and managing streaming platforms. This allows SMBs to unlock real-time insights from customer interactions, operations, or devices, without high upfront costs.
- Batch data processing: AWS Lambda is well-suited for batch data processing tasks that require substantial compute and storage resources for short periods of time. The service offers cost-effective, millisecond-billed compute that automatically scales out to meet processing demands and scales down upon completion. SMBs benefit from enterprise-level compute power without needing to maintain large, idle servers.
- Machine learning and generative artificial intelligence: AWS Lambda can preprocess data or serve machine learning models without infrastructure management, and it supports distributed, event-driven artificial intelligence workflows that scale automatically. This makes it easier for SMBs to experiment with AI use cases, like customer personalization or content generation, without deep technical overhead.
- Business process automation: Small businesses can use AWS Lambda for automating repetitive tasks such as invoice processing, data transformation, and document handling. For example, pairing AWS Lambda with Amazon Textract can automatically extract key information from invoices and store it in Amazon DynamoDB.

- Are there limits on environment variables for AWS Lambda functions?
Each Lambda function can store up to 4 kilobytes of environment variables. This limit includes all key-value pairs and can impact how much configuration or sensitive data is embedded directly in the function’s environment.
- How does AWS Lambda handle sudden traffic spikes in concurrency?
Lambda supports burst concurrency, allowing up to 500 additional concurrent executions every 10 seconds per function, or 5,000 requests per second every 10 seconds, whichever is reached first. This scaling behavior is critical for applications that experience unpredictable load surges.
- Is there a limit on ephemeral storage (/tmp) for AWS Lambda functions?
By default, each Lambda execution environment provides 512 megabytes of ephemeral storage in the /tmp directory, which can be increased up to 10 gigabytes if needed. This storage is shared across all invocations on the same environment and is reset between container reuses.
- Are there restrictions on the programming languages supported by AWS Lambda?
Lambda natively supports a set of languages (such as Python, Node.js, Java, and Go), but does not support every language out of the box. Using custom runtimes or container images can extend language support, but this comes with additional deployment and management considerations.
As data volumes continue to grow exponentially, small and medium-sized businesses (SMBs) face multiple challenges in managing, processing, and analyzing their data efficiently.
A well-structured data lake on AWS enables businesses to consolidate structured, semi-structured, and unstructured data in one location, making it easier to extract insights and inform decisions.
According to IDC, the global datasphere is projected to reach 163 zettabytes by the end of 2025, highlighting the urgent need for scalable, cloud-first data strategies.
This blog explores how SMBs can build effective ETL (Extract, Transform, Load) processes using AWS services and modernize their data infrastructure for improved performance and insight.

What is ETL?
ETL stands for extract, transform, and load. It is a process used to combine data from multiple sources into a centralized storage environment, such as an AWS data lake.
Through a set of defined business rules, ETL helps clean, organize, and format raw data to make it usable for storage, analytics, and machine learning applications.
This process enables SMBs to achieve specific business intelligence objectives, including generating reports, creating dashboards, forecasting trends, and enhancing operational efficiency.
Why is ETL important for businesses?
Businesses and mostly SMBs typically manage structured and unstructured data from a variety of sources, including:
- Customer data from payment gateways and CRM platforms
- Inventory and operations data from vendor systems
- Sensor data from IoT devices
- Marketing data from social media and surveys
- Employee data from internal HR systems
Without a consistent process in place, this data remains siloed and difficult to use. ETL helps convert these individual datasets into a structured format that supports meaningful analysis and interpretation.
By utilizing AWS services, businesses can develop scalable ETL pipelines that enhance the accessibility and actionability of their data.
The evolution of ETL from legacy systems to cloud solutions
ETL (Extract, Transform, Load) has come a long way from its origins in structured, relational databases. Initially designed to convert transactional data into relational formats for analysis, early ETL processes were rigid and resource-intensive.
1. Traditional ETL
In traditional systems, data resided in transactional databases optimized for recording activities, rather than for analysis and reporting.
ETL tools helped transform and normalize this data into interconnected tables, enabling fundamental trend analysis through SQL queries. However, these systems struggled with data duplication, limited scalability, and inflexible formats.
2. Modern ETL
Today’s ETL is built for the cloud. Modern tools support real-time ingestion, unstructured data formats, and scalable architectures like data warehouses and data lakes.
- Data warehouses store structured data in optimized formats for fast querying and reporting.
- Data lakes accept structured, semi-structured, and unstructured data, supporting a wide range of analytics, including machine learning and real-time insights.
This evolution enables businesses to process more diverse data at higher speeds and scales, all while utilizing cost-efficient cloud-native tools like those offered by AWS.
How does ETL work?
At a high level, ETL moves raw data from various sources into a structured format for analysis. It helps businesses centralize, clean, and prepare data for better decision-making.
Here’s how ETL typically flows in a modern AWS environment:
- Extract: Pulls data from multiple sources, including databases, CRMs, IoT devices, APIs, and other data sources, into a centralized environment, such as Amazon S3.
- Transform: Converts, enriches, or restructures the extracted data. This could include cleaning up missing fields, formatting timestamps, or joining data sets using AWS Glue or Apache Spark.
- Load: Places the transformed data into a destination such as Amazon Redshift, a data warehouse, or back into S3 for analytics using services like Amazon Athena.
Together, these stages power modern data lakes on AWS, letting businesses analyze data in real-time, automate reporting, or feed machine learning workflows.
What are the design principles for ETL in AWS data lakes?
Designing ETL processes for AWS data lakes involves optimizing for scalability, fault tolerance, and real-time analytics. Key principles include utilizing AWS Glue for serverless orchestration, Amazon S3 for high-volume, durable storage, and ensuring efficient data transformation through Amazon Athena and AWS Lambda. An impactful design also focuses on cost control, security, and maintaining data lineage with automated workflows and minimal manual intervention.
- Event sourcing and processing within AWS services
Use event-driven architectures with AWS tools such as Amazon Kinesis or AWS Lambda. These services enable real-time data capture and processing, which keeps data current and workflows scalable without manual intervention.
- Storing data in open file formats for compatibility
Adopt open file formats like Apache Parquet or ORC. These formats improve interoperability across AWS analytics and machine learning services while optimizing storage costs and query performance.
- Ensuring performance optimization in ETL processes
Utilize AWS services such as AWS Glue and Amazon EMR for efficient data transformation. Techniques like data partitioning and compression help reduce processing time and minimize cloud costs.
- Incorporating data governance and access control
Maintain data security and compliance by using AWS IAM (Identity and Access Management), AWS Lake Formation, and encryption. These tools provide granular access control and protect sensitive information throughout the ETL pipeline.
By following these design principles, businesses can develop ETL processes that not only meet their current analytics needs but also scale as their data volume increases.
AWS services supporting ETL processes
AWS provides a suite of services that simplify ETL workflows and help SMBs build scalable, cost-effective data lakes. Here are the key AWS services supporting ETL processes:
1. Utilizing AWS Glue data catalog and crawlers
AWS Glue data catalog organizes metadata and makes data searchable across multiple sources. Glue crawlers automatically scan data in Amazon S3, updating the catalog to keep it current without manual effort.
2. Building ETL jobs with AWS Glue

Steps to construct ETL pipelines in AWS
The how-to approach to ETL pipeline construction using AWS services, with Cloudtech guiding businesses at every stage of the modernization journey.
1. Mapping structured and unstructured data sources
Begin by identifying all data sources, including structured sources like CRM and ERP systems, as well as unstructured sources such as social media, IoT devices, and customer feedback. This step ensures full data visibility and sets the foundation for effective integration.
2. Creating ingestion pipelines into object storage
Use services like AWS Glue or Amazon Kinesis to ingest real-time or batch data into Amazon S3. It serves as the central storage layer in a data lake, offering the flexibility to store data in raw, transformed, or enriched formats.
3. Developing ETL pipelines for data transformation
Once ingested, use AWS Glue to build and manage ETL workflows. This step involves cleaning, enriching, and structuring data to make it ready for analytics. AWS Glue supports Spark-based transformations, enabling efficient processing without manual provisioning.
4. Implementing ELT pipelines for analytics
In some use cases, it is more effective to load raw data into Amazon Redshift or query directly from S3 using Amazon Athena.
This approach, known as ELT (extract, load, transform), allows SMBs to analyze large volumes of data quickly without heavy transformation steps upfront.
Best practices for security and access control
Security and governance are essential parts of any ETL workflow, especially for SMBs that manage sensitive or regulated data. The following best practices help SMBs stay secure, compliant, and audit-ready from day one.
1. Ensuring data security and compliance
Use AWS Key Management Service (KMS) to encrypt data at rest and in transit, and apply policies that restrict access to encryption keys. Consider enabling Amazon Macie to automatically discover and classify sensitive data, such as personally identifiable information (PII).
For regulated industries like healthcare, ensure all data handling processes align with standards such as HIPAA, HITRUST, or GDPR. AWS Config can help enforce compliance by tracking changes to configurations and alerting when policies are violated.
2. Managing user access with AWS Identity and Access Management (IAM)
Create IAM policies based on the principle of least privilege, giving users only the permissions required to perform their tasks. Use IAM roles to grant temporary access for third-party tools or workflows without compromising long-term credentials.
For added security, enable multi-factor authentication (MFA) and use AWS Organizations to apply access boundaries across business units or teams.
3. Implementing effective monitoring and logging practices
Use AWS CloudTrail to log all API activity, and integrate Amazon CloudWatch for real-time metrics and automated alerts. Pair this with AWS GuardDuty to detect unexpected behavior or potential security threats, such as data exfiltration attempts or unusual API calls.
Logging and monitoring are particularly important for businesses working with sensitive healthcare data, where early detection of irregularities can prevent compliance issues or data breaches.
4. Auditing data access and changes regularly
Set up regular audits of who accessed what data and when. AWS Lake Formation offers fine-grained access control, enabling centralized permission tracking across services.
SMBs can use these insights to identify access anomalies, revoke outdated permissions, and prepare for internal or external audits.
5. Isolating environments using VPCs and security groups
Isolate ETL components across development, staging, and production environments using Amazon Virtual Private Cloud (VPC).
Apply security groups and network ACLs to control traffic between resources. This reduces the risk of accidental data exposure and ensures production data remains protected during testing or development.
By following these practices, SMBs can build trust into their data pipelines and reduce the likelihood of security incidents.
