PROBLEM TO BE SOLVED: To stabilize an operating state of a system including a plurality of servers to improve its performance.SOLUTION: A system includes: a plurality of servers 111 and 112 operated by a predetermined function among a plurality of functions; detection means 151 for detecting operating states of the servers; and control means 152 for determining a change of functions by which the servers are operated on the basis of the operating states of the servers. A control device 150 stabilizes operating states of the servers in the system, by setting each of the servers 111 and 112 so that they are operated by the function whose change has been determined, and suppresses deterioration in their performance.SELECTED DRAWING: Figure 11 |
