A Content Delivery Network (CDN) is a distributed server system designed to deliver web content to users based on their geographic location. The goal of a CDN is to improve the performance and availability of a website by reducing the distance that data must travel between the user and the server.
Content Delivery Network (CDN) is made up of a network of servers strategically placed in various locations worldwide. When a user requests a web page, the CDN’s servers determine the user’s location and deliver the content from the server closest to the user rather than from the original server. This reduces the time it takes for the content to be delivered, improves the website’s load times, and reduces the risk of bottlenecks and outages.
Content Delivery Network (CDN) is commonly used to deliver various content, such as images, videos, and scripts, but they can also be used to deliver entire websites. They can also improve the security of a website by providing features such as Distributed Denial of Service (DDoS) protection and SSL encryption.
Examples of CDN providers include Akamai, Cloudflare, and Amazon CloudFront.
