The invention discloses a method and system for discovering and deploying available resources in a power cloud data center. The method comprises the following steps: step one, carrying out available resource discovery; to be specific, initiatively discovering new available resources in a power cloud data center; step two, carrying out device resource agent communication; to be specific, establishing a communication mechanism with newly discovered available resources; step three, carrying out modeling configuration management; to be specific, analyzing the newly discovered available resource situation, providing a piece of deployment model advice, allowing confirmation and adjustment by a user, and then generating a resource configuration template; and step four, carrying out configurationdeployment; to be specific, carrying out modeling configuration on a resource configuration template and deploying the newly discovered available resources. In a cloud computing data center environment, when a new resource device is connected to a cloud computing data center management network, automatic discovery of a newly added physical device, information collection, communication establishment, resource analysis, modeling configuration, automatic mounting and deployment, and final new resource online realization are carried out.
