In order to benefit from cloud computing services without risk, a good solution is building a private cloud in premise. This paper analyzes the advantages of a private cloud, through physical machine clusters and XEN virtualization technology, A private cloud topology is designed first, and analyze cache mechanism and load balancing policy of a private cloud infrastructure, then design a XEN-based private cloud infrastructure.
