Cloud//edge computing

Running code in datacenters geographically close to the user, rather than in a central region. Reduces latency because the request doesn't travel across continents.

Cloudflare has 300+ edge locations worldwide

The tradeoff: edge runtimes have limitations (no full Node.js, limited CPU time per request, restricted APIs)

Examples: Cloudflare Workers, Deno Deploy, Vercel Edge, AWS Lambda@Edge
