Auto-scale performance assurance system and auto-scale performance assurance method

An autoscale-type performance assurance system configured to perform autoscaling to increase or reduce, through addition or deletion, a number of virtual machines (VMs)/containers, which are either or both of VMs and containers generated in a network-connected server and resources typified by a central processing unit (CPU) and a memory of each of the number of VMs/containers, the autoscale-type performance assurance system comprising:

• a first server including:
• a plurality of types of the number of VMs/containers,
• a collection unit configured to collect a resource allocation amount of each of the number of VMs/containers, and
• a control unit configured to perform autoscaling to increase or reduce resources of each of the number of VMs/containers;
• and
• a second server including:
• a calculation unit configured to, based on the resource allocation amount that is collected, calculate a degree of dependency indicating whether the resource allocation amount is dependent on a performance related to the number of VMs/containers for providing a communication service quality, and
• a determination unit configured to obtain a resource control amount for increasing or reducing only resources related to the degree of dependency indicating being dependent that is calculated,
• wherein the control unit increases or reduces the resources related to the degree of dependency indicating being dependent of the number of VMs/containers by executing autoscaling according to the resource control amount obtained by the determination unit.
