Instantiating resources of an IT-service
First Claim
1. A method, comprising:
- analyzing a service model of an IT-service, the service model including a node representing a resource for providing the IT-service;
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.

Abstract
Instantiating a resource of an IT-service includes analyzing a service model of the IT-service where the service model includes a node representing a resource for providing the IT-service. A resource type of the resource being indicated by the node is determined, and a service provider catalog is evaluated to determine a resource manager operable to instantiate the resource and an address of the resource manager. A request is sent to the address of the resource manager for a description of a resource-manager-specific API of the resource manager. Upon receipt of the requested description, at least one abstract method for instantiating the resource is overridden with a resource-manager specific method of the resource-manager-specific API, and the resource-manager specific method for instantiating the resource represented by the node is executed.

8. A method, comprising:
-
identifying a plurality of resource managers each operable to provide a resource for providing an IT-service; 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. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method, comprising:
-
upon deployment of a resource manager operable to instantiate a resource of an IT-service, adding an entry to a service provider catalog of the resource manager, the entry being indicative of the resource manager, a resource type provided by the resource manager, and an address of the resource manager; receiving a request for a description of a resource-manager-specific API of the resource manager; sending, for the resource, the description to a management engine of an IT-service management system; sending, to the management engine, a description of a transmission protocol for enabling the management engine to interoperate with the resource manager via the resource-manager-specific API to instantiate the resource. - View Dependent Claims (15)
