A Content Delivery Network (CDN) is a geographically distributed network of servers that caches and delivers web content (images, CSS, JS, videos) from the server closest to the user. CDNs dramatically reduce latency and improve page load times by minimising the physical distance data must travel. Major CDN providers include Cloudflare, Fastly, AWS CloudFront, and Vercel's Edge Network. Modern frameworks like Next.js automatically leverage CDN distribution.
