Edge computing runs server-side code on CDN edge nodes — servers distributed globally near end users. Instead of a request traveling to a central server (200-500ms round trip), it hits the nearest edge node (10-50ms). Platforms: Cloudflare Workers, Vercel Edge Functions, Deno Deploy. Use cases: personalization, A/B testing, authentication, API routing, and any logic that benefits from low latency.
