A
content delivery network or
content distribution network (
CDN) is a globally distributed network of proxy
servers deployed in multiple
data centers. The goal of a CDN is to serve content to end-users with high availability and high performance. CDNs serve a large fraction of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals),
live streaming media, on-demand streaming media, and
social networks.
