EWPCC: An elastic Web proxy cache cluster basing on cloud computing

In order to relieve the conflict between improving service quality and enhancing resource efficiency in Web proxy cache cluster, a new elastic Web proxy cache cluster-EWPCC is presented. Basing on the “on demand” characteristic of cloud computing, EWPCC could acquire resource from cloud when the Web cache system is overloaded and release unnecessary cloud resource after load down. In this way, using local resource and cloud resource at the same time, EWPCC has high availability and reliability. Experiments' results show EWPCC could achieve outstanding performance and higher resource efficiency comparing with traditional Web proxy cache clusters.
