aws-serverless
Production-ready serverless patterns for AWS Lambda, API Gateway, DynamoDB, and event-driven architectures.
- Lambda handler structure with proper error handling, context optimization, and SDK client initialization for cold start efficiency
- API Gateway integration using SAM templates, supporting both HTTP and REST APIs with CORS configuration and IAM policies
- Event-driven SQS patterns with batch processing, partial failure handling, dead-letter queues, and retry logic
- Anti-patterns and sharp edges covering monolithic functions, large dependencies, VPC overhead, and timeout configuration
AWS Serverless
Specialized skill for building production-ready serverless applications on AWS. Covers Lambda functions, API Gateway, DynamoDB, SQS/SNS event-driven patterns, SAM/CDK deployment, and cold start optimization.
Principles
- Right-size memory and timeout (measure before optimizing)
- Minimize cold starts for latency-sensitive workloads
- Use SnapStart for Java/.NET functions
- Prefer HTTP API over REST API for simple use cases
- Design for failure with DLQs and retries
- Keep deployment packages small
- Use environment variables for configuration
- Implement structured logging with correlation IDs
