What is Serverless?
A cloud execution model where the provider manages servers and scales automatically.
Definition
Serverless computing lets you run code without provisioning or managing servers. Functions are triggered by events (HTTP requests, database changes, schedules) and scale automatically. You pay only for actual compute time. Services include AWS Lambda, Vercel Functions, Cloudflare Workers, and Google Cloud Functions. Despite the name, servers still exist — you just don't manage them. Ideal for APIs, webhooks, scheduled jobs, and event processing.
