Virtualization platform and scaling management method for virtualization platform

摘要

PROBLEM TO BE SOLVED: To provide a virtual platform which realizes high-speed and fine-grained scaling, and a scaling management method thereof. A virtualization platform includes a monitoring unit that monitors loads of a plurality of computes and loads of a virtual machine that is an execution environment running on the computes, and a scaling that determines whether to perform scaling and calculates a necessary resource amount. When the execution determination unit, the resource payout control unit that manages and allocates resources, and the scaling execution determination unit determine whether or not to perform scaling, the availability of resources for each compute is confirmed, and scale out, scale up, scale out, and scale A scaling method determination unit that selects one of the up-combined scaling methods and a scaling instruction unit that instructs the selected scaling method are provided.
