Abstract

An application manager receives or defines a service specification for a first application that defines a set of required computing resources that are necessary to run each application component of the first application. A resource supply manager in communication with the application manager manages a plurality of computing resources in a shared computing environment. The application manager is operable to request the set of required computing resources from the computing resource supply manager, and wherein the resource supply manager determines the availability of the required computing resources within the shared computing environment according to resource allocation policies and allocates computing resources to the application manager, and wherein the application manager is operable manage allocation of the computing resources to the first application, the application manager operable to create and manage deployment of instances of each application component of the first application on the allocated computing resources.

Claims

1. A system for managing a plurality of applications in a shared computing environment, each application comprising a plurality of application components, the system comprising:

a processor;

an application manager executable by the processor to receive a service specification for a first application that defines a set of required computing resources that are necessary to run each application component of the first application; and

a resource supply manager in communication with the application manager and operable to manage a plurality of computing resources in the shared computing environment;

wherein the application manager is operable to request the set of required computing resources from the computing resource supply manager, and wherein the resource supply manager determines the availability of the required computing resources within the shared computing environment according to resource allocation policies and allocates computing resources to the application manager, and wherein the application manager is operable manage allocation of the computing resources to the first application, the application manager operable to deploy and manage instances of each application component of the first application on the allocated computing resources.

2. The system of claim 1, wherein the plurality of applications are generally of heterogeneous types.

3. The system of claim 1, wherein the service specification also defines a set of constraints for the required computing resources, and wherein the application manager takes the constraints into account when requesting the set of computing resources from the resource supply manager.

4. The system of claim 3, wherein the constraints defines what computing resources can or cannot be allocated to the application manager to run the application components of the first application.

5. The system of claim 3, wherein the application manager can take into account the constraints of the first application in relation to the constraints of each other application when requesting the set of required computing resources from the resource supply manager.

6. The system of claim 3, wherein the constraints define the required computing resources in such a fashion that the application does not have a single point of failure.

7. The system of claim 1, wherein the service specification defines a priority for one or more of the plurality of applications, and wherein the application manager manages the plurality of applications taking into account said priorities.

8. The system of claim 1, wherein the application manager monitors the status of the allocated computing resources on which each application component is running, and where there is an instance of failure, restarting the application component that has failed on the corresponding allocated computing resource.

9. The system of claim 1, wherein the application manager monitors the status of the allocated computing resources on which each application component is running, and where there is an instance of failure, requesting a replacement computing resource from the resource supply manager and restarting the application component that has failed on the corresponding replacement computing resource.

10. An application manager installed on one or more computing devices, the one or more computing devices comprising a processor, the application manager operable to:

manage a plurality of applications in a shared computing environment, each application comprising a plurality of application components, the shared computing environment having a resource supply manager for managing a plurality of computing resources in the shared computing environment;

13. The application manager of claim 12, wherein the set of constraints defines what computing resources can or cannot be allocated to the application manager to run the application components of the first application.

14. The application manager of claim 12, wherein the application manager can take into account the constraints of the first application in relation to the constraints of each other application when requesting the set of required computing resources from the resource supply manager.

15. The application manager of claim 12, wherein the constraints define the required computing resources in such a fashion that the application does not have a single point of failure.

16. The application manager of claim 10, wherein the service specification defines a priority for one or more of the plurality of applications, and wherein the application manager manages the plurality of applications taking into account said priorities.

17. The application manager of claim 10, wherein the application manager monitors the status of the allocated computing resources on which each application component is running, and where there is an instance of failure, restarting the application component that has failed on the corresponding allocated computing resource.

18. The application manager of claim 10, The application manager of claim 10, wherein the application manager monitors the status of the allocated computing resources on which each application component is running, and where there is an instance of failure, requesting a replacement computing resource from the resource supply manager and restarting the application component that has failed on the corresponding replacement computing resource.

19. The application manager of claim 10, wherein the plurality of applications are adaptive for running in a heterogeneous resource environment.

20. A system for managing a plurality of applications in a shared computing environment, each application comprising a plurality of application components, the system comprising:

a processor;

an application manager executable by the processor to receive a service specification for a first application that defines a set of required computing resources that are necessary to run each application component of the first application; and

a resource supply manager in communication with the application manager and operable to manage a plurality of computing resources in the shared computing environment;

wherein the application manager is operable to request the set of required computing resources from the computing resource supply manager, and wherein the resource supply manager determines the availability of the required computing resources within the shared computing environment according to resource allocation policies and allocates computing resources to the application manager, and wherein the application manager is operable manage allocation of the computing resources to the first application, the application manager operable to dynamically initiate additional instances of one or more of the application components in response to increased demand for the first application.
