Provided is an information processing system that reflects a processing load of the virtual machine actually running in one server, and reproduces the processing load generated in the case where this virtual machine is run in the other server. An information processing system (1000) includes a server A(100) and a server B(200) that can communicate with each other through a network (500). The server A(100) runs a virtual machine (123), and transmits, to the server B(200), load information indicative of a processing load generated in the server A(100) as a result of running the virtual machine (123) when the virtual machine (123) is run. The server B(200) generates the processing load on the basis of the load information received from the server A(100).
