CDN (Content Delivery Network)

A CDN (Content Delivery Network) is a system of geographically distributed servers designed to deliver web and multimedia content to users more quickly and efficiently. The content is stored in various points of presence (PoPs) around the world, allowing data to be delivered from the location closest to the end user, thereby reducing latency and improving page load speed.

CDNs are essential for websites with heavy traffic and a global user base, as they improve the user experience by minimizing delays in content loading. They also help handle traffic spikes, provide security against denial-of-service (DDoS) attacks, and optimize content availability. Some popular examples of CDN providers include Akamai, Cloudflare, and Amazon CloudFront.
