Regular CDN features
Let's have a look at traditional CDN first. In simple words, CDN is a geographically distributed network of proxy servers and their data centers. Its goal is to distribute service spatially relative to end-users to provide high availability and high performance. CDNs serve a large part 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 media sites.
