Cold Starts & Performance Considerations

Part of the Cloud Computing Roadmap.

Summary

The delay when a serverless function hasn't run recently and needs to initialize before handling a request — a real performance consideration for latency-sensitive applications, with several mitigation strategies.

How to Learn This

  • 1Measure the response time difference between a 'cold' and a 'warm' function invocation.
  • 2Learn mitigation strategies: provisioned concurrency, smaller deployment packages, and runtime choice.
  • 3Understand why cold starts matter more for user-facing APIs than for background batch processing.
