Quick Reference

AWS Lambda: Initialize SDK clients outside handler for reuse. Use Powertools for structured logging/tracing. SnapStart for Java/Python cold starts. ARM64 (Graviton) for better price/performance. Layers for shared dependencies. Provisioned concurrency for strict latency. Cache secrets. Bundle with esbuild for TypeScript.

Use When

  • Building serverless functions
  • AWS Lambda development
  • Event-driven architectures
