CDN (Content Distribution Network)

This is a service that allows large, international websites to keep mirror copies of their websites hosted at different locations around the world to minimize latency of the web content, so that the request for the content does not have to go all the way to the original server, but instead can go to the nearest server with the content. Modern CDN’s also often offer other services to help with speed such as image hosting, processing and compression, JavaScript hosting, pre-processing and compression and other similar services.
