Network system, management server, and virtual machine deployment method

A management server included in a first cloud system in a network system including a plurality of cloud systems, each of the plurality of cloud systems including a plurality of servers, each of the plurality of servers allowing virtual machines to run thereon, the management server comprising:

• a generator configured to generate, on the basis of first performance information regarding one virtual machine and a predetermined coefficient predetermined for the first cloud system, second performance information regarding the one virtual machine, the first performance information being included in a first augmented image of the one virtual machine, the first augmented image being created in a second cloud system other than the first cloud system, the second cloud system being included in the plurality of cloud systems;
• and
• a deployer configured to deploy 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, wherein
• the second cloud system includes:
• a first acquirer configured to acquire third performance information regarding the one virtual machine in the second cloud system,
• a second generator configured to generate the first performance information by converting the acquired third performance information on the basis of a second coefficient predetermined for the second cloud system,
• an image creator configured to create an initial image of the one virtual machine, and
• an attacher configured to attach the generated first performance information to the created initial image to create the first augmented image.

A virtual machine deployment method executed by a network system including a plurality of cloud systems, each of the plurality of cloud systems including a plurality of servers, each of the plurality of servers allowing virtual machines to run thereon, the virtual machine deployment method comprising:

• generating, on the basis of first performance information regarding one virtual machine and a first predetermined coefficient predetermined for a first cloud system, second performance information regarding the one virtual machine by the first cloud system, the first performance information being included in a first augmented image of the one virtual machine, the first augmented image being created by a second cloud system other than the first cloud system, the second cloud system being included in the plurality of cloud systems;
• deploying, by the first cloud system, 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;
