Content delivery network

A content delivery network (CDN) is a geographically dispersed group of servers which collaborates to deliver internet material quickly.

A CDN enables the rapid transfer of resources such as HTML pages, javascript files, stylesheets, pictures, and videos that are required for Internet content to load. As CDN services gain more and more traction, they are now used to handle the vast majority of online traffic, including that coming from famous websites like Facebook, Netflix, and Amazon.

In addition to defending websites from some frequent malicious assaults, such as Distributed Denial of Service (DDOS) attacks, a correctly built CDN may also do so.
