Edge computing
Running code on servers physically near each user, spread around the world, for fast responses without managing regional data centers.
What it tells you about a developer
Edge experience is recent and still uncommon, so it marks a developer working close to the frontier of cloud platforms. It usually sits on top of solid backend or infrastructure experience, because writing for the edge means designing around strict limits on memory, time, and state. That constraint-driven thinking transfers well to any performance-sensitive system.
Edge computing runs code on the CDN's own servers, the ones already sitting near users, rather than in one central cloud region. The result is fast responses everywhere without managing regional deployments. Cloudflare Workers, AWS Lambda@Edge, and Vercel's edge functions are the main platforms. The code faces tight limits, so developers design small, fast programs that keep no memory between requests.
