摘要:
A network system includes a plurality of cloud systems. Each of the plurality of cloud systems includes a plurality of servers. Each of the plurality of servers allows virtual machines to run thereon. A first cloud system of the plurality of cloud systems includes a first generator and a deployer. The first generator generates, on the basis of first performance information regarding one virtual machine and a first predetermined coefficient predetermined for the first cloud system, second performance information regarding the one virtual machine. The first performance information is included in a first augmented image of the one virtual machine. The first augmented image is created in a second cloud system other than the first cloud system. The deployer deploys the one virtual machine on one of the plurality of servers included in the first cloud system on the basis of the generated second performance information.

A snapshot management method includes detecting a change in a configuration of a virtual machine; recording, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected; and determining a stable operation of the virtual machine by monitoring an operation status of the virtual machine and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition.

A method of managing a virtual machine by an information processing system including one or more information processing apparatuses, the method includes: comparing one or more files used for operation of the virtual machine with one or more template files; and generating configuration information indicating a setting state of the virtual machine based on a result of the comparing.
摘要:
This method includes: obtaining data of a first cost that represents a communication cost for communication with a processing apparatus that is included in a second system and carries out a processing by an application program for data held in the first system; calculating a second cost that represents a cost that occurs when the application program is disposed in the first system by using data of a charge for use of the application program and data of a cost required for maintenance and operation for an apparatus for carrying out a processing by the application program; determining whether a first condition including a second condition concerning a relationship between the first cost and the second cost is satisfied; and upon detecting that the first condition is satisfied, storing data representing that the first system is a system in which the application program is to be disposed.
