Abstract

A method for adjusting a central processing unit (CPU) utilization ratio of a cloud server of a datacenter using a remote server. The remote server sets a CPU utilization ratio range for a host operating system (OS) installed in a cloud server. The remote server calculates a score after the guest OS is transferred into the host OS, and calculates the score for revising CPU utilization ratio range after the guest OS is transferred out of the host OS. The remote server revises the CPU utilization ratio range according to the score.

Claims

1. A remote server, the remote server in electronic communication with a cloud server of a data center, the remote server comprising:

a storage system;

at least one processor; and

one or more programs stored in the storage system and being executable by the at least one processor, the one or more programs comprising;

a setting module sets a central processing unit (CPU) utilization range for a host operating system (OS) installed in the cloud server;

an obtaining module obtains a CPU utilization ratio of the host OS from the cloud server;

a transferring module transfers a guest OS from another cloud server of the data center into the host OS if the obtained CPU utilization ratio is less than a lower limit of the CPU utilization ratio range;

the transferring module further transfers the guest OS out of the host OS to the another cloud server if the obtained CPU utilization ratio is greater than an upper limit of the CPU utilization ratio range;

a calculating module calculates a score for revising the CPU utilization ratio range after the guest OS is transferred into the host OS, or calculates the score after the guest OS is transferred out of the host OS; and

a revising module revises the CPU utilization ratio range according to the score.

2. The remote server of claim 1, wherein the determination module further determines if a number of consecutive revised CPU utilization ratio ranges oscillate back and forth based on the lower or the upper limit of the CPU utilization ratio range.

3. The remote server of claim 1, wherein the score is a percentage value.

4. The remote server of claim 1, wherein the revising module revises the CPU utilization ratio range by amending the lower limit of the CPU utilization ratio range or the upper limit of the CPU utilization ratio range using the score.

5. The remote server of claim 1, wherein the obtaining module obtains the CPU utilization ratio of the host OS from a virtual machine management application installed in the cloud server.

6. The remote server of claim 1, wherein the transferring module transfers the guest OS using the virtual machine management application.

7. A computer-based CPU utilization ratio adjustment method being performed by execution of computer readable program code by a processor of a remote server, the remote server in electronic communication with a cloud server of a data center, the method comprising:

setting a central processing unit (CPU) utilization ratio range for a host operating system (OS) installed in the cloud server;

obtaining a CPU utilization ratio of the host OS from the cloud server;

transferring a guest OS from another cloud server of the data center into the host OS if the obtained CPU utilization ratio is less than a lower limit of the CPU utilization ratio range;

transferring the guest OS out of the host OS to the another cloud server if the obtained CPU utilization ratio is greater than an upper limit of the CPU utilization ratio range;

calculating a score for revising the CPU utilization ratio range after the guest OS is transferred into the host OS;

calculating the score after the guest OS is transferred out of the host OS; and

revising the CPU utilization ratio range according to the score.

8. The method of claim 7, further comprising:

determining if a number of consecutive revised CPU utilization ratio ranges oscillate back and forth based on the lower or the upper limit of the CPU utilization ratio range.

9. The method of claim 7, wherein the score is a percentage value.

10. The method of claim 7, wherein the range is revised by amending the lower limit of the CPU utilization ratio range or the upper limit of the CPU utilization ratio range using the score.

11. The method of claim 7, wherein the CPU utilization ratio of the host OS is obtained from a virtual machine management application installed in the cloud server.

12. The method of claim 7, wherein the guest OS is transferred using the virtual machine management application.

13. A non-transitory computer-readable medium having stored thereon instructions that, when executed by a remote server, the remote server in electronic communication with a cloud server of a data center, causing the remote server to perform a CPU utilization ratio adjustment method, the method comprising:

setting a central processing unit (CPU) utilization ratio range for a host operating system (OS) installed in the cloud server;

obtaining a CPU utilization ratio of the host OS from the cloud server;

transferring a guest OS from another cloud server of the data center into the host OS if the obtained CPU utilization ratio is less than a lower limit of the CPU utilization ratio range;

transferring the guest OS out of the host OS to the another cloud server if the obtained CPU utilization ratio is greater than an upper limit of the CPU utilization ratio range;

calculating a score for revising the CPU utilization ratio range after the guest OS is transferred into the host OS;

calculating the score after the guest OS is transferred out of the host OS; and

revising the CPU utilization ratio range according to the score.

14. The non-transitory medium of claim 13, wherein the method comprises:

determining if a number of consecutive revised CPU utilization ratio ranges oscillate back and forth based on the lower or the upper limit of the CPU utilization ratio range.

15. The non-transitory medium of claim 13, wherein the score is a percentage value.

16. The non-transitory medium of claim 13, wherein the range is revised by amending the lower limit of the CPU utilization ratio range or the upper limit of the CPU utilization ratio range using the score.

17. The non-transitory medium of claim 13, wherein the CPU utilization ratio of the host OS is obtained from a virtual machine management application installed in the cloud server.

18. The non-transitory medium of claim 13, wherein the guest OS is transferred using the virtual machine management application.
