Virtualization platform and virtualization platform scaling management method

Abstract

[Problem] To realize high-speed and fine-granularity scaling in a virtualization infrastructure. [Solution] A virtualization infrastructureincludes: a monitoring unit that monitors loads on a plurality of computes and loads on virtual machines that are execution environments operating on the plurality of computes; a scaling execution determination unit that determines execution of scaling and calculates a required resource amount; a resource dispensing control unit that manages and allocates a resource; a scaling method determination unit that, upon the determination of execution of scaling by the scaling execution determination unit, checks availability of the resource in each of the plurality of computes and selects any scaling method from the group consisting of scale-out, scale-up, and combined use of scale-out and scale-up; and a scaling indication unit that indicates the selected scaling method selected by the scaling method determination unit.
