A Content Delivery Network (CDN) is a large distributed system of servers deployed in multiple data centers on the Internet. It is an interconnected system of computers on the Internet that provides web content rapidly to numerous users by duplicating the content on multiple servers.
CDNs are used by Internet Service Providers (ISPs) to deliver static web-content, but this technology is especially well suited to streaming audio, video, and Internet Television (IPTV) programming. Availing CDN service for your domain is simple and affordable.
In CDN, your website's static content is cached on geographically spread POP servers. This content is refreshed every 60 minutes. When a visitor from Europe is trying to access your website hosted in the United States, all the static content is delivered to him from the nearest EU POP server.
