The article makes an introduction about research status at home and abroad and the related technology of cloud computing, emphatically introduces the architecture of cloud computing, virtualization and solution of existing cloud computing platform; In this paper, we made a thorough research and comparison between the two platforms in architecture and application, working principle, network architecture, security measures and so on, and concluded their scope of application and user colony. Based on the practical cloud as foothold, in view of the virtualization technology research, analyses the design of virtualized computing resources pool, the realization of the virtual machine live migration ability, etc, are discussed, trying to realize system's high availability and load balancing to build the aeronautical computer labs . And hope to provide some intends to explore and ideas for further research work.
