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