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.
