Abstract: A method, system, and computer program product are disclosed for automatically determining a valid ordering of provisioning operations, and their needed parameters, so that a provisioning system can configure a desired resource state. This is accomplished by formally describing the pre-conditions and effects of provisioning operations, the current state of managed resources and the desired final state. A planning algorithm is then used to determine the provisioning operations, a valid ordering and appropriate parameters to bring the system from the current state to the desired state.

Abstract: The present invention is directed to provisioning and managing computing services in a computing utility system. It receives as an input an infrastructure independent description of a set of requirements on the new desired state of a computing service. It uses a knowledge plane to represent the infrastructure. The method generates a Concrete Model that describes a resource structure that refines the input and is implementable over the infrastructure. It then generates and possibly executes provisioning actions to create an identical resource structure on the infrastructure. The method can be used to create new computing services, to destroy existing computing services, to modify the resource combinations allocated to a computing service, or the configuration of these resources. Provisioning actions can be executed immediately, or saved and executed later, and possibly many times.

Abstract: The present invention is directed to provisioning and managing computing services in a computing utility system. It receives a Concrete Resource Model describing a desired resource structure. It uses a representation of the infrastructure, including resources, configuration, capabilities and constraints, as a knowledge subsystem. The method generates and executes provisioning actions to affect the infrastructure resources by creating a resource structure that matches the description in the Concrete Resource Model and satisfies the requirements described in the input. The method can be used to create new computing services, to destroy existing computing services, to modify the resource combination allocated to a computing service, or the configuration of these resources. Provisioning actions, generated, can be executed immediately, or saved and executed later, and possibly many times.
