Abstract

Allocating computing resources comprises allocating an amount of a resource to an application program based on an established service level requirement for utilization of the resource by the application program, determining whether the application program'"'"'s utilization of the resource exceeds a utilization threshold, and changing the allocated amount of the resource in response to a determination that the application program'"'"'s utilization of the resource exceeds the utilization threshold. The utilization threshold is based on the established service level requirement and is different than the established service level requirement. Changing the allocation of the resource based on the utilization threshold allows allocating sufficient resources to the application program prior to a breach of a service level agreement for the application program.

Claims

1. A computer-implemented method for allocating computing resources, comprising the steps of:

allocating an amount of a resource to an application program based on an established service level requirement for utilization of the resource by the application program;

determining on a computer whether the application program'"'"'s utilization of the resource exceeds a utilization threshold, the utilization threshold being based on the established service level requirement and being different than the established service level requirement; and

changing via a computer the allocated amount of the resource in response to a determination that the application program'"'"'s utilization of the resource exceeds the utilization threshold.

2. The method of claim 1, wherein the amount of the resource allocated in the allocating step equals the service level requirement for the resource.

3. The method of claim 1, wherein the amount of the resource allocated in the allocating step is less than the service level requirement for the resource.

4. The method of claim 1, wherein the changing step occurs prior to the application program'"'"'s utilization of the resource exceeding the service level requirement.

5. The method of claim 1, wherein the changing step comprises allocating an additional amount of the resource to the application program, and wherein a total amount of the resource allocated to the application program is less than or equal to the service level requirement.

6. The method of claim 1, wherein the changing step comprises allocating an additional amount of the resource to the application program, and wherein a total amount of the resource allocated to the application program is greater than the service level requirement.

7. The method of claim 1, wherein the changing step comprises reducing an amount of the resource allocated to another program to obtain an additional amount of the resource that is then allocated to the application program.

8. The method of claim 1, wherein the changing step comprises migrating the application program to a different resource to obtain sufficient capacity based on the service level requirement for the application program.

9. The method of claim 1, wherein the changing step comprises migrating a family of application programs, including the application program, to a different resource to obtain sufficient capacity based on the service level requirement for the application program and to accommodate the family of application programs.

10. The method of claim 1, further comprising the step of adjusting the power or cooling requirements for the resource in response to changing the allocated amount of the resource.

11. The method of claim 1, wherein the changing step is based on a market exchange model.

12. The method of claim 1, further comprising repeating the allocating, determining, and changing steps for a plurality of resources and a plurality of application programs.

13. A computer-readable medium having computer-executable instructions for performing the computer-implemented method of claim 1.

14. A system for allocating computing resources, comprising:

a resource allocation manager that initially allocates an amount of a resource to an application program based on an established service level requirement for utilization of the resource by the application program; and

a quality of service (“

QOS”

) manager that determines whether the application program'"'"'s utilization of the resource exceeds a utilization threshold, the utilization threshold being based on the established service level requirement and being different than the established service level requirement,

wherein the resource allocation manager further changes the allocated amount of the resource in response to a determination that the application program'"'"'s utilization of the resource exceeds the utilization threshold.

15. The system of claim 14, further comprising a monitoring module that monitors the application program'"'"'s utilization of the resource and communicates the application program'"'"'s utilization of the resource to the QOS manager.

16. The system of claim 14, wherein the initial amount of the resource allocated to the application program equals the service level requirement for the resource.

17. The system of claim 14, wherein the initial amount of the resource allocated to the application program is less than the service level requirement for the resource.

18. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource prior to the application program'"'"'s utilization of the resource exceeding the service level requirement.

19. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource by allocating an additional amount of the resource to the application program, and wherein a total amount of the resource allocated to the application program is less than or equal to the service level requirement.

20. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource by allocating an additional amount of the resource to the application program, and wherein a total amount of the resource allocated to the application program is greater than the service level requirement.

21. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource by reducing an amount of the resource allocated to another program to obtain an additional amount of the resource that is then allocated to the application program.

22. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource by migrating the application program to a different resource to obtain sufficient capacity based on the service level requirement for the application program.

23. The system of claim 14, wherein the resource allocation manager changes the allocated amount of the resource by migrating a family of application programs, including the application program, to a different resource to obtain sufficient capacity based on the service level requirement for the application program and to accommodate the family of application programs.

24. The system of claim 14, further comprising a power adjustment system that adjusts power for the resource in response to the resource allocation manager changing the allocated amount of the resource.

25. The system of claim 14, further comprising a cooling adjustment system that adjusts cooling for the resource in response to the resource allocation manager changing the allocated amount of the resource.

26. The system of claim 14, wherein the resource allocation manager comprises a market exchange that allocates the resource based on a market exchange model.
