Executive Summary

A leading provider of SaaS solutions for OTT video delivery and media app development partnered with us to modernize their backend infrastructure and enhance their analytics platform on AWS. The project aimed to transition core APIs, user analytics, and media streaming orchestration to a cloud-native, serverless architecture. This modernization significantly improved platform scalability, reduced latency for global users, and enabled real-time analytics across content, user interactions, and overall performance.

Challenges

The customer faced several challenges that hindered scalability, performance, and operational efficiency:

  • API Modernization: Legacy, monolithic API services caused inefficiencies and limited scalability.
  • Global Latency: Content delivery, particularly video, had inconsistent performance for users across different regions.
  • Real-Time Analytics: A lack of real-time data insights made it difficult to track user engagement and optimize content.
  • Operational Complexity: High operational overhead due to manual processes and limited automation.
  • Disaster Recovery: Ensuring high availability and data redundancy was a top concern.

Scope of the Project

We were tasked with modernizing the SaaS platform by migrating core APIs and backend services to AWS microservices architecture. This involved microservice decomposition using Amazon API Gateway and AWS Lambda to replace monolithic API services. We also optimized video content delivery by utilizing CloudFront, S3, and MediaConvert for low-latency streaming and global delivery. A serverless analytics pipeline was built to process and analyze user events through Kinesis, Lambda, Redshift, and Glue. We ensured high availability by implementing multi-region failover with Route 53 and Aurora Global. Finally, CI/CD workflows were automated using CodePipeline, with monitoring and observability ensured through CloudWatch and X-Ray.

Partner Solution

We designed a fully serverless, scalable architecture using a combination of AWS Lambda for event-driven API services, CloudFront for global content delivery, and Redshift for analytics. The solution leverages Kinesis for real-time data ingestion, and Glue for data transformation and storage in S3.

The architecture includes:

  • API Gateway for routing requests to Lambda and ECS/Fargate microservices.
  • CloudFront for content delivery with S3 and MediaConvert integration.
  • Redshift for querying and analyzing user interaction data.
  • Aurora Global Database for cross-region failover and high availability.
  • AWS Backup for disaster recovery and cross-region replication of data.

Our Solution

API Modernization
  • Microservice Decomposition: We migrated monolithic APIs to a microservices-based architecture on AWS using API Gateway to manage routing and AWS Lambda to handle serverless execution.
  • ECS/Fargate: Containerized components are managed through Amazon ECS (Fargate) for flexible, cost-efficient compute.
  • API Gateway: Securely exposed the APIs to the frontend, validating requests and integrating with backend services using IAM roles for access control.
Streaming Optimization
  • CloudFront CDN: Used CloudFront to cache content at the edge, reducing latency and speeding up content delivery globally.
  • S3 & MediaConvert: Leveraged Amazon S3 for storage and MediaConvert for adaptive bitrate transcoding, enabling smooth video streaming on various devices.
  • Global Distribution: Ensured optimal performance and reduced buffering by using CloudFront to serve video content efficiently to users across the globe.
Real-Time Analytics Pipeline
  • Data Ingestion: Kinesis Data Streams was used to ingest user interaction events (e.g., play, pause, share) in real time.
  • Data Enrichment: AWS Lambda processed and enriched the data streams before being stored in S3.
  • ETL with Glue: AWS Glue performed ETL (Extract, Transform, Load) processes, converting data into an analytical format for consumption by Redshift.
  • Analytics: Amazon Redshift was used for fast querying and reporting, enabling real-time insights into user behavior.
High Availability and Fault Tolerance
  • Multi-AZ Deployment: Deployed critical services like Redshift and Aurora Global in multiple Availability Zones to ensure high availability.
  • Route 53 Failover: Set up Route 53 with latency-based routing and health checks to ensure automatic failover between regions if one region faces issues.
  • Auto-Scaling: Configured Auto Scaling Groups and ALB to automatically scale compute resources based on demand.

Benefits

  • Enhanced Streaming Performance: By implementing CloudFront and MediaConvert, video buffering was reduced by >90% and latency minimized across regions.
  • Real-Time Analytics: The Redshift + Glue pipeline enabled real-time analytics, empowering the customer to optimize user engagement based on live data insights.
  • Operational Efficiency: Automating CI/CD with CodePipeline and using serverless components significantly reduced manual intervention, lowering operational overhead by 40%.
  • High Availability: Route 53 routing and Aurora Global deployment ensured 99.95% uptime across regions, offering the customer peace of mind.
  • Scalable Storage: Using S3 Intelligent-Tiering and Redshift Concurrency Scaling provided optimal storage management, ensuring cost efficiency as data grew.

Outcome (Business Impact)

  • Enhanced User Satisfaction: Reduced video buffering to <3%, improving content delivery speed and user experience globally.
  • Improved Match Accuracy: Real-time Redshift + Glue pipelines improved engagement tracking, reducing query times from 30s to <5s.
  • Operational Efficiency: Automation through CI/CD and serverless components cut manual intervention by 40%, increasing overall team productivity.
  • High Availability: Route 53 and Aurora Global ensured 99.95% uptime, even during regional outages.
  • Cost Efficiency: Optimized storage with S3 Intelligent-Tiering and Redshift Concurrency Scaling drove down operational costs.
With AWS, we’ve reduced our root cause analysis time by 80%, allowing us to focus on building better features instead of being bogged down by system failures.
