Serverless

Definition

Serverless computing lets you run code without managing servers. You write functions, deploy them to a platform, and only pay when they run. The platform handles scaling, patching, and infrastructure automatically.

Simple Explanation

Traditional hosting is like renting a full restaurant kitchen. Serverless is like ordering room service — you only pay when you use it, and someone else maintains everything.

Real-World Use Case

An e-commerce site has a function that sends order confirmations. You deploy it, it runs when someone places an order, and you pay pennies per invocation.
