How Cloudflare Workers Created a New Programming Paradigm: Edge Computing

Cloudflare Workers pioneered edge computing for developers, running code in 300+ locations worldwide with sub-millisecond cold starts. Unlike traditional cloud (code runs in one region), Workers run at the edge closest to users. The paradigm shift: instead of scaling compute (add more servers), you scale geography (add more locations). Workers uses V8 isolates (not containers), enabling millions of instances per machine. This architecture enables new patterns: geo-distributed apps, A/B testing by region, local compliance, and ultra-low latency APIs. R2 and D1 complete the edge platform, moving storage and database to the edge too.
