ServerlessMicroservicesPlatform

Architected a serverless platform for microservices using AWS Lambda, API Gateway, and DynamoDB.

Overview

The Serverless Microservices Platform is a cloud-native architecture designed to enable rapid development and deployment of scalable, event-driven microservices without managing traditional server infrastructure. This platform leverages AWS serverless technologies to provide a flexible foundation for building modern applications with automatic scaling, pay-per-use pricing, and reduced operational overhead.

Challenges

•Designing for stateless, event-driven architecture
•Managing cold starts and performance optimization
•Implementing effective service discovery and API management
•Ensuring data consistency across distributed services
•Developing a comprehensive monitoring and debugging strategy

Solutions

•Implemented domain-driven design principles for service boundaries
•Used provisioned concurrency and code optimization for critical paths
•Created an API Gateway with custom authorizers and usage plans
•Designed event-sourcing patterns with DynamoDB streams
•Deployed X-Ray tracing with custom subsegments for observability

Results & Impact

•Reduced infrastructure costs by 60% compared to container-based solution
•Achieved sub-100ms response times for 95% of API requests
•Eliminated operational overhead for scaling during traffic spikes
•Decreased time-to-market for new features by 50%
•Improved developer productivity with streamlined deployment process
