AWS Lambda & Serverless

Part of the Backend Developer Roadmap.

Summary

Running backend code as individual functions that execute on-demand and scale automatically, without managing any servers — you pay only for actual execution time.

How to Learn This

  • 1Deploy a simple function to AWS Lambda and trigger it via API Gateway.
  • 2Learn the trade-offs: no idle cost and automatic scaling, but cold starts and execution time limits.
  • 3Compare when serverless fits (spiky, event-driven workloads) vs when a traditional server fits better.
