Abstract

A computer implemented method, data processing system, and computer usable program code are provided for maintaining a computer network. Resources and services affected by a change to a resource are identified in response to receiving a request for the change. A determination of an optimal time for the change is made based on a policy associated with the service. The change is deployed with a deployment engine.

Claims

1. A computer implemented method for maintaining a computer network, the computer implemented method comprising:

responsive to receiving a request for a change to a resource, identifying resources and services affected by the change, wherein the services are a set of high-level services, wherein the identifying step further comprises;

retrieving an object dependency graph for the at least one high-level service;

identifying the at least one high-level services represented by a root of the object dependency graph;

scanning a service and state repository to identify the object dependency graph; and

determining whether the change is permitted to be implemented according to policies, wherein the policies are retrieved from a policy database;

determining, by a processor, an optimal time for the change based on the policies associated with the services; and

deploying the change with a deployment engine.

2. The computer implemented method of claim 1, wherein the computer network is a grid-based infrastructure of computing devices.

3. The computer implemented method of claim 1, wherein the change is requested in a federated system.

4. The computer implemented method of claim 1, wherein the services are a set of high-level services, wherein the set of high-level services is executed by an enterprise.

5. The computer implemented method of claim 4, wherein the identifying step further comprises:

retrieving an object dependency graph for the at least one high-level service.

6. The computer implemented method of claim 5, wherein the retrieving step further comprises:

determining if the change affects a node of the object dependency graph; and

responsive to a determination that the change will affect the node, retrieving the object dependency graph associated with the node.

7. The computer implemented method of claim 4, wherein the determining step further comprises:

retrieving policies associated with each of the at least one high-level service.

8. The computer implemented method of claim 6, wherein the policies are retrieved from a policy database.

10. The computer implemented method of claim 1, further comprising:

making the change consistent with policies, wherein the change is made by the deployment engine.

11. The computer implemented method of claim 10, wherein the making step further comprises:

configuring and deploying the change to resources.

12. The computer implemented method of claim 1, further comprising:

invoking a workflow to make the change, wherein the deployment engine executes the workflow to make the change.

13. The computer implemented method of claim 1, wherein the identifying step and determining step are performed by a change management coordinator;

and

wherein the change is received from a system administrator or another change management coordinator.

14. The computer implemented method of claim 1, wherein the change is any of a hardware change, a software change, and a configuration change.

9. A computer implemented method for maintaining a computer network, the computer implemented method comprising:

responsive to receiving a request for a change to a resource, identifying resources and services affected by the change, wherein the services are a set of high-level services, wherein the set of high-level services is executed by an enterprise, wherein the identifying step further comprises;

retrieving an object dependency graph for the at least one high-level service, wherein the retrieving step further comprises;

determining, by a processor, if the change affects a node of the object dependency graph; and

responsive to a determination that the change will affect the node, retrieving the object dependency graph associated with the node;

identifying the at least one high-level services represented by a root of the object dependency graph;

scanning a service and state repository to identify the object dependency graph; and

determining whether the change is permitted to be implemented according to policies, wherein the policies are retrieved from a policy database;

determining, by the processor, an optimal time for the change based on the policies associated with the services; and

deploying the change with a deployment engine.

15. A change management system comprising:

a bus system;

a storage device connected to the bus system; and

a processor unit connected to the bus system configured to communicate with a change management coordinator interface for receiving a request from an administrator or other change management coordinators, and wherein the processor is further configured to communicate with a change management coordinator wherein the change management coordinator identifies resources and services affected by a change to a resource in response to receiving a request for the change, wherein the services are a set of high-level services, retrieves an object dependency graph for the at least one high-level service, identifies the at least one high-level services represented by a root of the object dependency graph, scans a service and state repository to identify the object dependency graph, determines whether the change is permitted to be implemented according to policies, wherein the policies are retrieved from a policy database determines an optimal time for the change based on a policy associated with a service and stored in a policy database within the change management coordinator, and schedules and coordinates the change with a deployment engine.

16. The change management system of claim 15, wherein the change management coordinator receives the change from another change management coordinator or a system administrator through a change management coordinator interface,

wherein the change management coordinator identifies resources and services affected by retrieving an object dependency graph associated with the resources and services stored within a services and state repository operably connected to a processor,

wherein the policy is retrieved from the policy database operably connected to the processor.

17. The change management system of claim 15, wherein the change management coordinator invokes a workflow to be implemented by the deployment engine for making the change.

18. A computer program product comprising a computer readable storage device including computer usable program code for maintaining a computer network, said computer program product comprising:

responsive to receiving a request for a change to a resource for, computer usable program code for identifying resources and services affected by the change, wherein the services are a set of high-level services, wherein the identifying step further comprises;

computer usable program code for retrieving an object dependency graph for the at least one high-level service;

computer usable program code for identifying the at least one high-level services represented by a root of the object dependency graph;

computer usable program code for scanning a service and state repository to identify the object dependency graph; and

computer usable program code for determining whether the change is permitted to be implemented according to policies, wherein the policies are retrieved from a policy database;

computer usable program code for determining an optimal time for the change based on a policy associated with the services; and

computer usable program code for deploying the change with a deployment engine.

19. The computer program product of claim 18, further comprising:

computer usable program code for invoking a workflow to make the change, wherein the deployment engine executes the workflow to make the change.
