The Rise of the Dynamic Edge
summary
Claim: running full apps on the edge cuts latency and simplifies ops. Uses Cloudflare Workers (200+ locations, V8 isolates, 1 MB script limit, no cold starts), HTTP tactics like s-maxage and stale-while-revalidate to reduce origin load to roughly one request per CDN node per minute, and a compiler approach (fab.dev) that turns apps into a single entrypoint plus assets. Benchmarks show dynamic routes drop from ~1.5s tail to ~400ms on the edge; Next.js needs extra compilation but other frameworks perform even better.
