Summary:PROBLEM TO BE SOLVED: To update files quickly without preparing for additional resources and affecting services in a decentralized processing system.SOLUTION: When updating files in each of servers of a decentralized processing system, a management device commands each server to create a new virtual machine for file update to allocate an address to the new virtual machine. The management device also allocates resources to the new virtual machine from excess resources of the server to perform file update toward each of the new virtual machines. Then, the management device stops a LB (load balancer), updates a distribution destination in address information to the address of the new virtual machine, and restarts the LB. 【課題】分散処理システムにおいて、追加リソースを用意しなくても、サービスに影響を与えることなく、速やかにファイル更新を行う。【解決手段】管理装置は、分散処理システムのサーバそれぞれのファイル更新を行うとき、サーバそれぞれに、ファイル更新用の新たな仮想マシンを作成させ、新たな仮想マシンに対しアドレス割り当てを行う。また、管理装置は、新たな仮想マシンに対し、サーバの余剰リソースからリソースの割り当てを行い、新たな仮想マシンそれぞれに対しファイル更新処理を行う。その後、ＬＢ（ロードバランサ）を閉塞し、アドレス情報における振り分け先を新たな仮想マシンのアドレスに更新し、ＬＢの閉塞を解除する。【選択図】図３
