TechnologyLesson on requestFree to read

Quick answer

Serverless computing lets developers run code without managing servers themselves. The cloud provider automatically runs and scales the code only when it's needed, and you pay just for what you use — though servers still exist behind the scenes. You run code without managing servers yourself.

Key things to understand

  1. You run code without managing servers yourself.
  2. The cloud provider handles scaling automatically.
  3. You pay only for actual usage, not idle time.
  4. Servers still exist — they're just abstracted away.
