CDN (Content Delivery Network)
A globally distributed network of servers that caches and delivers content from locations geographically close to users. CDNs reduce latency, improve load times, and absorb traffic spikes. They rely heavily on HTTP caching headers (Cache-Control, ETag, Expires) to determine what to cache and for how long. Cloudflare, AWS CloudFront, and Fastly are popular CDN providers.
