Virtualization Solution
Virtualization means that the computer system operates in virtual platform rather than real platform. Virtualization technology can fully utilize hardware resource and simplify the rearrangement process of the software. The virtualization technology of CPU can simulate multiple paralleled CPU with one CPU and allow the operation of multiple operating systems in one platform. In addition, the applications can operate in mutually independent spaces without affecting each other, thus the working efficiency of the computer is greatly improved.

Virtualization solution (as shown in the picture) installs virtualization software on multiple physical servers to form virtual cluster. It realizes running multiple virtual machines on one physical server, which saves time and space; through virtualization cluster, dynamic migration of one virtual machine on multiple physical servers can be realized. When one virtual machine is down, the virtual machine can be migrated to other servers online to guarantee the continuity of the business; besides, the deployment of virtual machine can be done rapidly through copying template to fasten the deployment of new business systems.
