Content Delivery Network (CDN)
Jul/093
A content delivery network or CDN is a computer network specialized for delivery of specific type of content. This type of networks specialize in content replication on targeted or global basis.
A content delivery network consists of points of access which allow certain content to be served to end users. The main benefit from such a network is the ability to serve a large number of users simultaneously and possibly on a global scale. A CDN can provide the means to deliver content to a huge number of users while maintaining reasonable cost of scaling. A CDN s total bandwidth capacity can go way beyond a single backbone connection that a DC would have.
If you need to deliver a large “amount” of content to a large number of users a using a CDN is the only way to do it. Microsoft for instance uses about a dozen of CDN’s for hire to deliver content to end users.
