A content delivery network, also referred to as a content distribution network (CDN) is a geographically distributed network of data centers containing proxy servers. CDN Providers serve Internet content, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, etc… closer to and thus faster, to end users. Some of the main advantages of using a CDN are: improved load times, reduced bandwidth costs, increased availability and improved security.
