Rebuilding and the private cloud of the hospital information system by the virtualization technology.

In our hospital, we managed an electronic health record system and many section subsystems as a hospital information system. By the expansion of these information systems, a system becomes complicated, and maintenance and operative cost increased. Furthermore, the environment that is available to medical information is demanded anywhere anytime by expansion of the computerization. However, the expansion of the information use becomes necessary for the expansion such as the personal protection of information for security. We became rebuilding and the private cloud of the hospital information system by the virtualization technology to solve such a problem. As a result, we were able to perform a decrease in number of the servers which constituted a system, a decrease in network traffic, reduction of the operative cost.
