Abstract

Instantiating a resource of an IT-service includes: analyzing a service model including nodes representing resources and being indicative of a resource type, each node comprising a generic API providing at least one abstract method for instantiating the resource represented by the respective node. For each node, determining the resource type indicated by the node; evaluating a service provider catalog indicative of a resource manager operable to provide a resource of a given resource type and determining an address of the resource manager; selecting a resource manager; sending a request to the address of the selected resource manager for a description of a resource-manager-specific API of the resource manager; receiving the requested description from the selected resource manager; overriding the abstract method by a resource-manager specific method of the resource-manager-specific API for instantiating the resource; and executing the overridden abstract method for instantiating the resource represented by the node.

Claims

1. A system, comprising:

a resource for providing an IT-service; and

a management engine computer having a management engine configured for;

analyzing a service model of the IT-service, the service model comprising a node representing the resource;

determining a resource type of the resource being indicated by the node;

evaluating a service provider catalog to determine a resource manager being operable to instantiate the resource and an address of the resource manager;

sending a request to the address of the resource manager for a description of a resource-manager-specific API of the resource manager;

receiving the requested description from the resource manager;

overriding at least one abstract method for instantiating the resource with a resource-manager specific method of the resource-manager-specific API, the resource-manager specific method being specified in the received description; and

executing the resource-manager specific method for instantiating the resource represented by the node.

2. The system of claim 1, wherein the resource manager includes a catalog registration unit for adding, upon deployment of a further resource manager, an entry to the service provider catalog indicative of the further resource manager.

3. The system of claim 1, wherein the resource manager is further configured for, upon deployment of the resource manager, adding an entry to the service provider catalog, the entry being indicative of the resource manager, the resource type provided by the resource manager, and the address of the resource manager.

4. The system of claim 3, wherein the resource manager is further configured for, upon receipt of the request from the management engine, sending the description of the resource manager-specific API to the management engine.

5. The system of claim 1, wherein the node is a node of a graph, and wherein analyzing the service model comprises traversing the graph for instantiating the resource represented by the graph'"'"'s node in accordance with a topology of the graph.

6. The system of claim 1, wherein the service model is indicative of a chronological sequence of a plurality of resources to be instantiated, the sequence being specified by a topology of a graph.

7. The system of claim 1, wherein the management engine is further configured for:

evaluating the received description for determining a data transmission protocol to be used by the management engine for interoperating with the resource manager;

determining one or more API methods and API parameters to be used by the management engine for interoperating with the resource manager; and

wherein the interoperation is executed by the determined transmission protocol and/or by the determined API methods and API parameters.

8. A computer program product for instantiating a resource of an IT-service, the computer program product comprising a non-transitory storage medium comprising program instructions which, when executed by a processor, cause the processor to execute a method comprising:

analyzing a service model of the IT-service, the service model comprising a node representing the resource;

determining a resource type of the resource being indicated by the node;

evaluating a service provider catalog to determine a resource manager being operable to instantiate the resource and an address of the resource manager;

sending a request to the address of the resource manager for a description of a resource-manager-specific API of the resource manager;

receiving the requested description from the resource manager;

overriding at least one abstract method for instantiating the resource with a resource-manager specific method of the resource-manager-specific API, the resource-manager specific method being specified in the received description; and

executing the resource-manager specific method for instantiating the resource represented by the node.

9. The computer program product of claim 8, wherein the method further comprises adding, upon deployment of a further resource manager, an entry to the service provider catalog indicative of the further resource manager.

10. The computer program product of claim 8, wherein the method further comprises, upon deployment of the resource manager, adding an entry to the service provider catalog, the entry being indicative of the resource manager, the resource type provided by the resource manager, and the address of the resource manager.

11. The computer program product of claim 10, wherein the method further comprises, upon receipt of the request from a management engine, sending the description of the resource manager-specific API to the management engine.

12. The computer program product of claim 8, wherein the node is a node of a graph, and wherein analyzing the service model comprises traversing the graph for instantiating the resource represented by the graph'"'"'s node in accordance with a topology of the graph.

13. The computer program product of claim 8, wherein the service model is indicative of a chronological sequence of a plurality of resources to be instantiated, the sequence being specified by a topology of a graph.

14. The computer program product of claim 8, wherein the method further comprises:

evaluating the received description for determining a data transmission protocol to be used by a management engine for interoperating with the resource manager;

determining one or more API methods and API parameters to be used by the management engine for interoperating with the resource manager; and

wherein the interoperation is executed by the determined transmission protocol and/or by the determined API methods and API parameters.

15. A system, comprising:

a plurality of resource managers each operable to provide a resource for providing an IT-service; and

a management engine computer having a management engine configured for;

analyzing a service model of the IT-service, the service model comprising nodes representing the respective resources, the nodes specifying a generic API, the generic API not being specific to any resource managers and providing at least one abstract method for instantiating the resource represented by the respective node;

selecting one of the nodes;

evaluating a service provider catalog and selecting one of the resource managers being operable to instantiate the resource as indicated by the selected node;

sending a request to the selected resource manager for a description of a resource-manager-specific API of the resource manager;

overriding the abstract method for instantiating the resource with a resource-manager specific method of the resource-manager-specific API; and

executing the resource-manager specific method for instantiating the resource represented by the node.

16. The system of claim 15, wherein the nodes are nodes of a graph, and wherein analyzing the service model comprises traversing the graph for instantiating the resource represented by the graph'"'"'s node in accordance with a topology of the graph.

17. The system of claim 15, wherein the service model is indicative of a chronological sequence of a plurality of resources to be instantiated, the sequence being specified by a topology of a graph.
