![]() ![]() Let's use an example to get a clearer understanding of how CDN works. Companies typically purchase content delivery network services from content delivery network providers, who manage and maintain their network of servers. The percentage keeps rising as more and more enterprises expand their reach to newer markets and offer more diverse types of content. The content delivery network, by bringing web content nearer to end-users, allows website publishers to control bandwidth consumption, reduce load times, and provide enhanced performance.Ĭontent delivery networks currently serve over 50 percent of the world's web traffic. The goal of CDN is to facilitate increased web performance and high availability by locating web content copies closer to the end-users.ĬDN servers are often referred to as "edge servers" since all CDN servers are located on the "edge network" - closer to end-users than a host server from which an application or a website originates.ĬDN servers store or cache copies of various web content subsets from a host server, such as applications, video, audio, images, and HTML files. What Is CDN?Ī content delivery network (CDN) is a geographically dispersed network of servers and data centers. So, what does CDN stand for? CDN is the short for "content delivery network," which is one of the core components responsible for the accelerated delivery of dynamic Internet content across the globe. Why do some websites keep crashing, while there are countless others that deliver superior performance in similar situations? Well, the performance differs because of CDN. If you access the Internet via a smartphone, tablet or computer, it is natural for you to notice the differences in speed, reliability, and user experience of different applications and websites. ![]()
