Content Delivery Network(CDN)
A network of distributed servers that cache content closer to users.
A Content Delivery Network caches website content on servers distributed globally, serving each user from the geographically nearest server. CDNs dramatically reduce latency, improve page speed, and reduce origin server load. Major CDNs include Cloudflare, AWS CloudFront, Fastly, Vercel Edge Network, and Akamai.
Example
A Canadian e-commerce site adds Cloudflare CDN. Visitors in Europe load pages in 600ms instead of 2.4s (because content serves from London edge servers instead of round-tripping to Toronto).
