Virtual machine placement determination apparatus, virtual machine placement determination method, and virtual machine placement determination program

摘要

A virtual machine placement plan search unit 1 that searches and enumerates virtual machine placement plans that satisfy resource constraints, and an availability that reflects the configuration of the application for each virtual machine placement plan and indicates the probability that the application is in an operating state An availability model synthesizing unit 2 that generates an availability model for calculating the availability model, an application availability evaluation unit 3 that analyzes the availability model and calculates an availability evaluation value indicating the availability of the application system constructed by the virtual machine placement plan, A virtual machine placement ranking unit 4 that ranks each virtual machine placement plan based on the availability evaluation value and determines a virtual machine placement plan to be applied to the application.
