How do Cloudflare Workers compare to AWS Lambda?

Cloudflare Workers use V8 isolates rather than containers, eliminating cold starts entirely and offering consistent sub-millisecond initialization. Lambda provides broader language support, longer execution times, and deeper AWS service integration. Workers excel for edge API, auth, and request manipulation; Lambda excels for backend event processing.

Which Lambda alternative has the most generous free tier?

Google Cloud Functions offers 2 million free invocations per month. Azure Functions provides 1 million free requests. Cloudflare Workers free tier allows 100,000 daily requests. Lambda's free tier is 1 million requests per month. Vercel and Netlify's free tiers are usage-limited but generous for hobby projects.

What should I consider when migrating from AWS Lambda to another FaaS platform?

Key considerations include runtime language support, maximum execution duration, cold start latency, VPC integration, event source connectors, deployment tooling, observability integration, and pricing model (per-request vs per-GB-second). Many platforms support Lambda-compatible runtimes to ease migration.
