Edge Computing Basics
Edge computing moves computation from centralized data centers to locations closer to end users.
Why Edge
- Latency: round-trip times drop from 100ms to 10ms
- Bandwidth: filter and process data before sending it upstream
- Resilience: continue operating during network outages
Typical Stack
- Cloudflare Workers, Vercel Edge Functions, or Deno Deploy
- Key-value stores at the edge (Cloudflare KV)
- Static assets served from 300+ locations
The edge is ideal for personalization, A/B testing, authentication checks, and API gateways.
