Electronic device and method for managing computing resources of at least one cloud server for providing cloud service

A method of managing computing resources of at least one cloud server that provides a cloud service by using a virtual machine instance, the method comprising:

• receiving, from a client device, at least one service request for a service provided by the virtual machine instance;
• executing, a process of the virtual machine instance for the service based on the received at least one service request;
• changing a modes of the virtual machine instance for managing of the computing resources as a sleep mode, based on at least one of a time at which the service corresponding to the at least one service request is provided or a characteristic of the service corresponding to the at least one service request;
• migrating data stored in a vCPU and a vRAM of the virtual machine instance to a vDisk of the virtual machine instance and deactivating the vCPU and the vRAM of the virtual machine instance, based on the changing to the sleep mode,
• changing the mode of the virtual machine instance from the sleep mode to a deep sleep mode when a service request for the service is not received from the client device for a predetermined period from the time when the mode of the virtual machine instance is changed to the sleep mode;
• storing only a data of the vCPU from among the migrated data to the vDisk, based on the changing to the deep sleep mode;
• and
• migrating the data of the vCPU migrated to vDisk to the vCPU and executing the process of the virtual machine instance for the service by using the data migrated to the vCPU, when a service request for the service is received from the client device in the deep sleep mode,
• wherein the virtual machine instance is generated by the at least one cloud server.

A computer program product comprising a non-transitory computer readable storage medium,

• the computer readable storage medium comprising instructions for managing computing resources of at least one cloud server that provides a cloud service by using a virtual machine instance,
• wherein the managing of the computing resources of the at least one cloud server comprises:
• receiving, from a client device, at least one service request for a service provided by the virtual machine instance;
• executing, a process of the virtual machine instance for the service based on the received at least one service request;
• changing a modes of the virtual machine instance for managing of the computing resources as a sleep mode, based on at least one of a time at which the service corresponding to the at least one service request is provided or a characteristic of the service corresponding to the at least one service request;
• migrating data stored in a vCPU and a vRAM of the virtual machine instance to a vDisk of the virtual machine instance and deactivating the vCPU and the vRAM of the virtual machine instance, based on the changing to the sleep mode,
• changing the mode of the virtual machine instance from the sleep mode to a deep sleep mode when a service request for the service is not received from the client device for a predetermined period from the time when the mode of the virtual machine instance is changed to the sleep mode;
• storing only a data of the vCPU from among the migrated data to the vDisk, based on the changing to the deep sleep mode;
• and
• migrating the data of the vCPU migrated to vDisk to the vCPU and executing the process of the virtual machine instance for the service by using the data migrated to the vCPU, when a service request for the service is received from the client device in the deep sleep mode,
• wherein the virtual machine instance is generated by the at least one cloud server.
