Title:
COMPUTER SYSTEM AND AUTOSCALING METHOD FOR COMPUTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/075771
Kind Code:
A1
Abstract:
A computer system having a varying load, wherein computer resources are appropriately allocated according to the load even when load variations are difficult to predict and even when different computer resource allocation methods are effective for different application conditions. In order to accomplish this feature, the computer system is at least provided with: a physical server which has computer resources including a processor, a storage device, and a communication interface; a virtualization device which virtualizes computer resources and allocates virtual computer resources to a plurality of virtual environments; and a management device which manages the plurality of virtual environments. The management device comprises: a monitoring unit which monitors loads on the plurality of virtual environments; a control unit which determines, based on the monitored loads, whether it is necessary to add another virtual environment; and a configuration changing unit which requests addition of a virtual environment in accordance with the determination made by the control unit, removes usage restrictions on computer resources that constitute existing virtual environments, and, upon completion of the addition of a virtual environment, restores the usage restrictions on the existing virtual environments.
