Summary:PROBLEM TO BE SOLVED: To suppress an occurrence of a failure based on a time required by the time an increased virtual machine operates when the virtual machine is increased in a system for providing a service with a virtual machine as a server.SOLUTION: The system includes: a request holding part 130 for holding a request for causing an execution server 200 to execute processing: a transmission and reception part 110 for transmitting the request held by the request holding part 130 to the execution server 200; and an execution server management part 160 for managing information of the execution server 200, and increasing a resource of the execution server 200 in the case that a state of the execution server 200 based on a load of processing to a request during execution of the execution server 200 and a predicted load of processing in the execution server 200 when processing to the request held by the request holding part 130 is executed satisfy a predetermined specific condition.SELECTED DRAWING: Figure 2 【課題】仮想マシンをサーバとしてサービスを提供するシステムにおいて、仮想マシンを増加させた際に、増加した仮想マシンが稼働するまでに要する時間に基づく不具合の発生を抑制する。【解決手段】実行サーバ200に処理を実行させる要求を保持する要求保持部130と、要求保持部130に保持された要求を実行サーバ200へ送信する送受信部110と、実行サーバ200の情報を管理し、実行サーバ200が実行中の要求に対する処理の負荷と要求保持部130に保持されている要求に対する処理が実行される場合に予想される実行サーバ200における処理の負荷とに基づく実行サーバ200の状態が、予め定められた特定の条件を満足する場合に、実行サーバ200の資源を増加させる実行サーバ管理部160と、を備える。【選択図】図2
