Content Delivery Network (CDN)
A CDN is a globally distributed network of edge servers that caches content close to the end user, dramatically reducing load times.
A CDN (Cloudflare, Fastly, Akamai, BunnyCDN) stores copies of your static — and often dynamic — content on hundreds of edge locations worldwide. A visitor from Tokyo then fetches your CSS in Tokyo, not from your Amsterdam server. Effect: TTFB and LCP tumble, server load drops, DDoS protection comes for free.
Example
A Dutch shop expands into Germany and France. Without CDN the site loads in Berlin in 3.2s; with Cloudflare, 1.1s. DE bounce rate halves.
