The Future of CDNs is Here Today
CDNs were originally designed to improve the performance of web sites by pushing graphics and embedded images out to a network of edge-caching servers, thus speeding transmission times by delivering that content from the server geographically closest to the end user. However, as enterprise use of the Internet has increased over the years, demands have also increased, and only today's best CDNs are able to keep up with businesses' evolving needs.
The term CDN - content delivery network - may qualify as a misnomer today. CDNs aren't just for traditional web site content anymore. Bottlenecks on the Internet, the underlying problem that led to the development of CDNs, remain. However, leading CDNs are now able to provide companies with powerful, reliable support for both static and dynamic content - including high-impact, high-bandwidth multimedia content that has historically been difficult to deliver reliably over the public Internet.
