In simpler words, CDN’s purpose is to improve user experience by enhancing network routing for the resources. The best way to reduce latency is to decrease the distance between the source and the destination. The more the distance between the server and browser, the more will be the latency. Network latency is the time taken by the data to transfer from the source to the destination. To understand it more clearly, you have to understand Network Latency. When multiple requests are being made to fetch the data from one place, the loading speed gets slow, which negatively affects the User Experience. Loading Speed is directly proportional to User Experience. Google ranks fast loading sites, and users like to interact with the fast loading pages. The importance of the loading speed of the webpage is not unknown. The process stops bottlenecks happening near the central server by providing the data to users from servers near them.ĬDN is also known as Distribution Network, which again means distributing the content to the multiple locations and then providing the content to the users. The browser does not have to fetch the data from the central location but from the server that is geographically closer to the user. A copy of the content is replicated and stored at the multiple edge server of CDN. Instead of storing the content in one place (traditional method), that is, the central server, CDN method is far more efficient. Architecture of Content Delivery NetworkĪ CDN or Content Delivery Network is a globally distributed web server and Points of Presence network to accelerate content delivery.In this post we will learn about the CDN. All the large sites, and eCommerce stores are using it. CDN or Content Delivery Network is a critical part of the content delivery process via Internet.
