Overview

AWS Lambda lets you run code in response to events without managing servers, with a generous free tier suitable for many workloads and easy scaling.

Good fit

Use Lambda for event-driven workloads, APIs, or automation where you want to avoid server management and scale automatically.

  • event-driven apps
  • microservices
  • automation scripts

Not a fit

Avoid Lambda for long-running processes, heavy compute workloads, or when you need predictable, sustained performance.

  • need long-running compute
  • require low-latency at scale
  • prefer dedicated servers
