Content delivery network

A content delivery network or content distribution network (CDN) is a large distributed system of servers deployed in multiple data centers across the Internet. The goal of a CDN is to serve content to end-users. A CDN operator gets paid by content providers such as media companies and e-commerce vendors for delivering their content to their audience of end-users. In turn, a CDN pays ISPs, carriers, and network operators for hosting its servers in their data centers.

@Reviewer: I don't know much about this technology. The description above is from Wikipedia. Perhaps someone with better knowledge of this can edit the wiki. I just added this to bring this tag without wiki into spotlight.
