Cloudflare Workers: Serverless at the Edge

Cloudflare Workers represent a decisive break in serverless computing, executing code at the edge in over 300 locations worldwide. Unlike traditional serverless platforms that run in centralized data centers, Workers run within milliseconds of your users, dramatically reducing latency. This comprehensive guide explores Workers architecture, use cases, and implementation strategies for building globally distributed applications.

Understanding Cloudflare Workers

Workers are built on V8 isolates, the same technology powering Chrome. This architecture provides near-instantaneous cold starts (< 5ms) compared to traditional containers (seconds).
