Abstract
A management application refers to an application management table, and acquires the operation states of all VMs included in an additional application of which the priority related to the execution of a job that has requested from the image forming apparatus. The management application detects the additional application including only VM that is not executing processing based on the operation states of the acquired VMs, and deletes the VM included in the detected additional application.
Claims7
A cloud computing system comprising:
- a request reception unit configured to be realized by executing a request reception program that stores a message corresponding to a job in a storage unit in response to the reception of a processing request for the job from an information processing apparatus;
- a back-end processing unit configured to be realized by executing a back-end processing program that makes an acquisition request for the message to the storage unit at regular intervals, and when the message has been acquired from the storage unit, performs processing based on the acquired message;
- wherein a plurality of the back-end processing units is activated in the cloud computing system, and each back-end processing unit is incorporated into a processing execution unit that functions as an application, and
- a deletion unit configured not to delete an application that includes the process execution unit that is executing processes based on the message, but to delete the process execution unit that includes applications other than this application.

A method for controlling a cloud computing system, the method comprising:
- storing a message corresponding to a job in a storage unit in response to the reception of a processing request for the job from an information processing apparatus by a request reception unit configured to be realized by executing a request reception program,;
- and
- processing an acquisition request for the message to the storage unit at regular intervals, and when the message has been acquired from the storage unit, performing processing based on the acquired message by a back-end processing unit configured to be realized by executing a back-end processing program,
- wherein a plurality of the back-end processing units is activated in the cloud computing system, and each back-end processing unit is incorporated into a processing execution unit that functions as an application, and
- not deleting the application that includes the process execution unit that is executing a process based on the message but deleting the process execution units that include applications other than this application.
