VDI RESOURCE ALLOCATION DETERMINATION DEVICE, VDI RESOURCE ALLOCATION DETERMINATION METHOD, AND VDI RESOURCE ALLOCATION DETERMINATION PROGRAM

A virtual desktop (VDI) resource allocation decision apparatus that decides resource allocation of a VDI apparatus according to an embodiment includes an input unit that receives a performance requirement defining performance to be satisfied by the VDI apparatus and a specified time zone indicating a time zone in which the performance requirement is satisfied, a resource allocation collection and storage unit that stores a current resource allocation including a number of virtual machines included in a host of the VDI apparatus and a virtual calculation resource allocated to a virtual machine, a workload collection and storage unit that stores a workload of the VDI apparatus, and a calculation function unit that applies the specified time zone and the workload to a workload prediction model to calculate a workload in the specified time zone, applies the workload in the specified time zone and the current resource allocation to a performance model to calculate first performance of the VDI apparatus, and determines whether or not the first performance meets the performance requirement.
