Content Delivery Network
A content delivery network is a group of servers that is geographically located to enable faster web performance by caching copies of web content closer to users or facilitating the delivery of dynamic content. Each CDN server is called the network edge, closer to users than the host server, which is where the website originates. Each server stores or caches copies of a subset of the Static Web Content content like HTML Pages, Images, Audio, and Videos from the host server. By reducing the distance between this content and users, the content delivery network helps the website publisher provide faster performance, and reduce loading time for its users.
