Computer procurement prediction apparatus, computer procurement prediction method, and program

摘要

In order to predict the time when it is necessary to add a computer on which the VM is placed considering demand fluctuation of the VM, rearrangement of the computation period, and load fluctuation, the computer procurement timing prediction device is deployed in a plurality of computers Calculates a predicted value of the number of VMs generated from time t-t to t based on the demand fluctuation statistics showing the generation condition of the required virtual machine (VM) (hereinafter referred to as VM), and is allocated to the computer at time t-t Based on the load fluctuation statistics showing the load fluctuation of the VMs on the plurality of computers, the VM demand forecasting means for adding the number of VMs registered in the placement target list to the placement target list in which the number of VMs registered , VM load fluctuation predicting means for outputting a predicted load at time t, VMs registered in the placement target list virtually on the plurality of computers at the time t based on the predicted load, Does it occur And VM allocation control virtual execution means for judging whether or not the VM allocation control is possible.
