A closer look at a content delivery network implementation

Success in Internet applications involves user interactions whose quality is mainly affected by the application response time.

Their effectiveness of this network have been shown in large companies such as Akamai and Speedera.

This article tries to describe a CDN from a different point of view that pays more attention on the implementation process of the CDN.
