Edge Computing

TechConcept

Edge computing is an architectural model where compute runs as close to the end user as possible — on geographically distributed points of presence (PoPs) — rather than in a single, distant cloud region.

Edge computing is an architectural model where compute runs as close to the end user as possible — on geographically distributed points of presence (PoPs) — rather than in a single, distant cloud region.

The goal is to reduce latency (code responds within tens of milliseconds even on the other side of the world) and to offload origin servers. It has become a standard for web rendering (Vercel Edge, Cloudflare Workers, Netlify Edge Functions, Deno Deploy), personalisation, authentication and request routing.

Edge runtimes are typically more constrained than a full Node.js (no filesystem, limited APIs) because they run in V8 isolates rather than containers.
