Cloudflare Workers for Edge Applications

Edge applications reduce latency by moving logic closer to users. Cloudflare Workers provide a lightweight runtime that can handle routing, APIs, authentication checks, and caching near the request source.

The biggest wins come from small pieces of logic: redirects, API gateways, personalization, and cache orchestration. Not every workload belongs at the edge.

Design for platform limits. Keep CPU work short, stream when possible, and store state in the right binding such as KV, D1, R2, Durable Objects, or Queues.
