Abstract

An application resource manager obtains a projection of upcoming demand for an application that runs on a cloud. The cloud includes at least one of an infrastructure as a service cloud and a platform as a service cloud. The application resource manager determines, based on the projection, that resources of the cloud that are devoted to the application need to be one of extended and shrunken. One of extending and shrinking the resources of the cloud that are devoted to the application is carried out in response to the determining.

Claims

1. A method comprising:

obtaining, by an application resource manager, a projection of upcoming demand for an application that runs on a cloud, said cloud comprising at least one of an infrastructure as a service cloud and a platform as a service cloud;

determining, by said application resource manager, based on said projection, that resources of said cloud that are devoted to said application need to be one of extended and shrunken; and

carrying out one of extending and shrinking said resources of said cloud that are devoted to said application, in response to said determining step.

2. The method of claim 1, wherein said obtaining comprises obtaining said projection from an application owner.

3. The method of claim 1, wherein said obtaining comprises said application resource manager deriving said projection based on observations of at least one of:

said application; and

data from a cloud management interface of said cloud.

4. The method of claim 1, wherein said determining comprises determining that said resources of said cloud that are devoted to said application need to be shrunken, and wherein said carrying out comprises carrying out shrinking by stashing unused images in said cloud.

5. The method of claim 1, wherein said determining comprises determining that said resources of said cloud that are devoted to said application need to be extended, and wherein said carrying out comprises carrying out said extending by provisioning new images in said cloud.

6. The method of claim 5, further comprising said application resource manager provisioning at least one of application level software and data onto said new images.

7. The method of claim 1, further comprising at least one of:

running said application resource manager on said cloud; and

running said application resource manager on a computing resource other than said cloud.

8. The method of claim 1, wherein said determining comprises finding a most cost-effective way to fulfill said projected upcoming demand.

9. The method of claim 1, wherein, in said obtaining step, said projected upcoming demand is specified in terms of at least one of performance and availability.

10. The method of claim 1, further comprising said application resource manager periodically running a discovery tool to detect changes to at least one of:

said application; and

said resources of said cloud that are devoted to said application.

11. The method of claim 1, further comprising providing a system, wherein the system comprises distinct software modules, each of the distinct software modules being embodied on a computer-readable storage medium, and wherein the distinct software modules comprise an application resource manager module, a management sub-module, and a control sub-module;

wherein;

said obtaining is carried out by said application resource manager module executing on at least one hardware processor;

said determining is carried out by said management sub-module executing on said at least one hardware processor; and

said one of extending and shrinking is carried out by said control sub-module executing on said at least one hardware processor.

12. The method of claim 11, wherein:

said distinct software modules further comprise a policies sub-module and an interpretation sub-module;

said determining is carried out by said management sub-module, executing on said at least one hardware processor, implementing at least one policy of said policies sub-module and based on at least one of utilization information and failure reports from said interpretation sub-module.

13. A system comprising:

a cloud, said cloud comprising at least one of an infrastructure as a service cloud and a platform as a service cloud;

at least one application that runs on said cloud; and

an application resource manager;

wherein said application resource manager;

obtains a projection of upcoming demand for said application;

determines, based on said projection, that resources of said cloud that are devoted to said application need to be one of extended and shrunken; and

carries out one of extending and shrinking said resources of said cloud that are devoted to said application, in response to said determining.

14. The system of claim 13, wherein said application resource manager obtains said projection from an application owner.

15. The system of claim 13, wherein said cloud comprises a cloud management interface and wherein said application resource manager obtains said projection by deriving said projection based on observations of said application and data from said cloud management interface of said cloud.

16. The system of claim 13, wherein:

at least some of said resources of said cloud that are devoted to said application comprise images;

said application resource manager determines that said resources of said cloud that are devoted to said application need to shrunken; and

said application resource manager carries out said shrinking by stashing unused ones of said images.

17. The system of claim 13, wherein said application resource manager determines that said resources of said cloud that are devoted to said application need to extended, and wherein said application resource manager carries out said extending by provisioning new images in said cloud.

18. The system of claim 13, wherein:

said application resource manager in turn comprises a management portion and a control portion;

said management portion of said application resource manager determines, based on said projection, that said resources of said cloud that are devoted to said application need to be one of extended and shrunken; and

said control portion of said application resource manager carries out said one of extending and shrinking said resources of said cloud that are devoted to said application, in response to said determining.

19. An application resource manager computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, said computer readable program code comprising:

computer readable program code configured to obtain a projection of upcoming demand for an application that runs on a cloud, said cloud comprising at least one of an infrastructure as a service cloud and a platform as a service cloud;

computer readable program code configured to determine, based on said projection, that resources of said cloud that are devoted to said application need to be one of extended and shrunken; and

computer readable program code configured to specify instructions for carrying out one of extending and shrinking said resources of said cloud that are devoted to said application, in response to said determining.

20. The computer program product of claim 19, wherein said computer readable program code configured to obtain said projection comprises computer readable program code configured to obtain said projection from an application owner.

21. The computer program product of claim 19, wherein said computer readable program code configured to obtain said projection comprises computer readable program code configured to derive said projection based on observations of at least one of:

said application; and

data from a cloud management interface of said cloud.

22. The computer program product of claim 19, wherein said computer readable program code configured to determine comprises computer readable program code configured to determine that said resources of said cloud that are devoted to said application need to be shrunken, and wherein said instructions specify carrying out shrinking by stashing unused images in said cloud.

23. The computer program product of claim 19, wherein said computer readable program code configured to determine comprises computer readable program code configured to determine that said resources of said cloud that are devoted to said application need to be extended, and wherein said instructions specify carrying out said extending by provisioning new images in said cloud.
