CONNECTION CONTROL DEVICE FOR VIRTUAL MACHINE, CONNECTION CONTROL SYSTEM FOR VIRTUAL MACHINE, CONNECTION CONTROL METHOD FOR VIRTUAL MACHINE, AND PROGRAM

摘要

A connection control device (100) for a virtual machine is provided with a data collection unit (110) that acquires VNF performance measured by arranging virtual machines constituting the application to be verified in all combinations in at least two servers, a coupling degree analysis unit (120) that calculates a coupling degree related to a communication delay between the virtual machines on the basis of the measurement data of VNF performance acquired, a competing degree analysis unit (130) that calculates a competing degree related to a decrease in VNF performance between the virtual machines on the basis of the measurement data of VNF performance acquired, and a scaling control unit (150) that determines the arrangement of the virtual machines having a VNF performance that exceeds a predetermined threshold on the basis of the coupling degree and competing degree calculated.
