On the aspect of the availabililty of information service platform, this paper describes the basic concepts and features of virtual machine, compares and analyses the typical cases of them, and expatiates the detailed realization processes of the high available platform for information services based on virtual machine. The high availability of the service platform is realized by network load balancing to distribute workload evenly in the access intensive virtual applications, and by the methods of resource hypervisor, live migration, virtual snapshots, et al. in the light virtual applications.
