What it shows

  • API Gateway offloads auth, TLS, and request throttling at the edge
  • AWS Lambda scales execution on demand with zero idle server cost
  • DynamoDB single-table design delivers single-digit millisecond latency

The takeaway

Serverless APIs eliminate idle infrastructure costs while scaling seamlessly from zero to 10k+ req/sec.
