Serverless does not mean "no servers" — it means you do not manage them. You write functions, upload them, and the cloud provider handles infrastructure, scaling, and availability. You pay only for execution time (often fractions of a cent per request). Major platforms: AWS Lambda, Cloudflare Workers, Vercel Edge Functions, Netlify Functions. Serverless is ideal for API endpoints, webhooks, scheduled tasks, and event processing. It is not ideal for long-running processes, WebSocket connections, or applications needing persistent state.
