What is the Windows Azure Content Delivery Network?
A content delivery network (CDN) enhances end user performance and reliability by placing copies of data, at various points in a network, so that they are distributed closer to the user. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same set of central servers (called Origins), thereby causing a bottleneck near these Origin servers. Content types include web objects (e.g. JPG, CSS, and JavaScript), downloadable objects (media files, software, documents) and other components for Internet delivery. Windows Azure CDN supports HTTP delivery of public content stored in Windows Azure storage.
