Virtualization platform and virtualization platform scaling management method

A virtualization infrastructure scaling management method comprising:

• obtaining, by a resource monitoring unit, utilization data that represents (i) loads on a plurality of computes and Iii) loads on execution environments operating on the plurality of computes;
• comparing, by a scaling execution determination unit, the obtained utilization data to a threshold value;
• determining, by the scaling execution determination unit, the obtained utilization data satisfies the threshold value;
• in response to determining the obtained utilization data satisfies the threshold value, calculating, by a scaling execution determination unit, a required resource amount based on the obtained utilization data;
• in response to calculating the required resource amount, determining, by a scaling method determination unit, whether the resource is present in each of the plurality of computes that mounts an execution environment;
• determining, by the scaling method determination unit, that a sum of available resources in any compute of the plurality of computes on which the execution environment is operating is larger than an additional resource;
• in response to determining that the sum of available resource in any compute of the plurality of computes is larger than the additional resource, selecting, by the scaling method determination unit, a scaling method of scale up;
• indicating, by a scaling indication unit, the selected scaling method and the required resource amount to be scaled up to a resource dispensing control unit;
• managing, by the resource dispensing control unit, a resource in each of the plurality of computes;
• allocating, by the resource dispensing control unit, the resource to each of the execution environments;
• adding, by the resource dispensing unit, the required resource amount to a corresponding execution environment of a compute according to the selected scaling method.
