The present invention relates to a system for providing virtual machines that provides virtual machines virtualized on a physical server to each user.
There is a virtual server distributed arrangement method including: generating server arrangement data that represents correspondence relation between a virtual server identifier representing each one of a plurality of virtual servers and a physical server identifier representing each one of a plurality of physical servers arranging the virtual servers in a distributed manner; generating virtual server configuration data that represents correspondence relation between a virtual server identifier and a group identifier used for identifying a user group using the virtual server; calculating an evaluation value of the virtual server arrangement that is arranged in accordance with the server arrangement data based on the virtual server identifier and the group identifier; and displaying a plurality of candidates for the virtual server arrangement based on the calculated evaluation values (see Patent Literature 1). According to this virtual server distributed arrangement method, virtual computers can be appropriately arranged for a physical computer, and thereby a loss in the user section can be minimized.
According to the virtual server distributed arrangement method disclosed in Patent Document 1 described above, the virtual servers are not assigned separately to each user based on the use frequency, the use form and the user method of a user using the virtual servers, and the virtual servers cannot allow users to effectively use the virtual servers without any waste in correspondence with the use frequency and the use form of the virtual server, and the use method of each user. In addition, virtual servers having mutually-different capacities cannot be assigned to each user in accordance with a request of the user, and virtual servers having mutually-different capacities corresponding to the use frequency, the use form, and the use method of each user cannot be used by the user. According to this virtual server distributed arrangement method, the virtual servers are visualized for users using the virtual servers, and a virtual server of one user may be changed by another user, and thereby it is difficult to acquire the security of the virtual servers.
