Infrastructure

CDN

A global network of servers that caches your files close to users so they load fast.

Instead of every visitor hitting your one server in Virginia, a CDN keeps copies of your assets — images, JavaScript, static HTML — in data centers worldwide and serves each person from the nearest one. This slashes latency and absorbs sudden traffic spikes without melting your origin server. Analogy: instead of shipping every pizza from one kitchen, you open franchises in every city. As a vibe coder you usually get this for free — deploy to Vercel or Netlify and your static assets land on a CDN automatically.
