Cloud//AWS//Lambda

Amazon's serverless functions. The original serverless compute platform (launched 2014). Each invocation spins up a function, executes, and dies.

Runs inside containers (not V8 isolates like Workers) — heavier, but supports more languages and longer execution times

Cold starts are real: first invocation after idle takes 100ms–1s+ depending on language and bundle size. The container has to boot.

Execution limit: up to 15 minutes (vs Workers' 30s paid / 5min max)

Vercel Functions are Lambda under the hood — Vercel abstracts the deployment, AWS runs the code

Pricing: per invocation + per GB-second of compute. Free tier: 1M requests/month
