Abstract: Provided is power consumption estimation means that can accurately estimate the power consumption of diverse applications. A power consumption estimating device includes a metadata DB that stores past application metadata related to each of past applications, a power consumption DB including power consumption information representing the power consumption of the past applications, and a power consumption estimating section that estimates the power consumption of an estimation target application.

Abstract: To estimate power consumption of a workload, an estimation server estimates power consumption of a workload executed on a physical server. A processor trains a plurality of short-range power models that receive a metric of the physical server as an input and output a power consumption value of the physical server in a plurality of short ranges obtained by dividing an entire power range of the physical server into a predetermined division number, trains a classifier that receives a metric of the physical server as an input and outputs specification information specifying a corresponding short range and specifies specification information specifying a short range to be applied based on a metric of the workload and the classifier. The estimate of the power consumption of the workload is based on the metric of the workload and a short-range power model corresponding to the short range indicated by the specification information.
