A CDN is not the same as a web host

To understand why CDNs are so widely used, you first need to recognize the problem they were designed to solve. This problem, known as latency , is the annoying amount of time it takes from the moment you want to load a web page to the moment the content actually appears on the screen. This latency range is affected by a number of factors, many of which are specific to a particular web page. However, in all cases, latency is affected by the physical distance between you and the website’s hosting server. The mission of a CDN is to shorten this physical distance, and its goal is to improve site rendering speed and performance.


While a CDN does not host content and cannot nepal phone number library replace the need for proper web hosting, it does help cache content at the edge of the network, which improves website performance. Many websites struggle to meet their performance needs with traditional hosting services, which is why CDNs are becoming more popular. So by using caching to reduce hosting bandwidth, help prevent service outages, and increase security, CDNs are becoming a popular choice to alleviate some of the major pain points that come with traditional web hosting.

How Does CDN Work?

To minimize the distance between visitors and your website’s server, a CDN stores a cached version of its content in multiple geographic locations. Each POP contains a number of caching servers responsible for delivering content within proximity to its visitors.



Essentially, a CDN is a network of servers connected together for the purpose of delivering content as quickly, cheaply, reliably and securely as possible. To improve speed and connectivity, a CDN will place servers at interchange points between different networks.

These Internet Exchange Points (IXPs) are the primary locations where different Internet providers connect to access traffic originating from their disparate networks. By connecting to these high-speed, interconnected locations, a CDN provider can reduce costs and transit times for high-speed data delivery.
