Abstract:
1. A cloud computing system including a group of server computers, the cloud computing system comprising: an initial request reception unit configured to receive a connection request from a device configured to transmit the connection request, a service usage request, and service identification information, wherein the initial request reception unit includes a notification unit configured to notify the device of information required to identify a request reception unit configured to receive a service usage request; a request reception unit configured, in a case where the device has tried to access the request reception unit based on the information required to identify a request reception unit, to receive a service usage request and service identification information transmitted from the device, wherein the request reception unit includes a determination unit configured to determine, based on the received service identification information, whether a back-end processing unit is present that both corresponds to the device and is configured to execute the service; and a transmission unit configured, in a case where the determination unit determines that a back-end processing unit that both corresponds to the device and is configured to execute the service is present, to transmit a service utilization preparation completion screen to the device without instructing generation of an instance that can realize the back-end processing unit and, in a case where the determination unit determines that a back-end processing unit that both corresponds to the device and is configured to execute the service is not present, to send an instance generation instruction to a management unit configured to manage instances and to further send an instruction to launch an instance generated to execute the service, wherein after the instance is launched and the back-end processing unit is realized, the transmission unit further is configured to transmit the service utilization preparation completion screen to the device, wherein the request reception unit further is configured to transmit the service utilization preparation completion screen to the device if it is determined that a service instance is present.
