Abstract: A method, apparatus, and computer instructions are provided for a common cluster model for configuring, managing, and operating different clustering technologies in a data center. The common cluster model supports peer cluster domains and management server cluster domains. Each cluster domain may have one or more cluster nodes. For each cluster domains, one or more cluster resources may be defined. These resources may depend on one another and may be grouped into a resource group. A set of cluster domain and cluster resources logical device operations are provided to configure, manage, and operate cluster domains and its associated resources.

Abstract: A resource broker is used in managing workloads of a peer-to-peer distributed computing environment. The broker is responsible for distributing to a plurality of clients of the peer-to-peer distributed computing environment tasks of one or more workloads of one or more issuers of the environment. The tasks are processed by the clients using a runtime environment provided by the broker. The runtime environment of a client is generic to the one or more issuers and independent of an operating system of the client.

Abstract: A method, apparatus, and computer instructions are provided for expressing high availability (H/A) cluster demand based on probability of breach. When a failover occurs in the H/A cluster, event messages are sent to a provisioning manager server. The mechanism of embodiments of the present invention filters the event messages and translates the events into probability of breach data. The mechanism then updates the data model of the provision manager server and makes a recommendation to the provisioning manager server as to whether reprovisioning of new node should be performed. The provisioning manager server makes the decision and either reprovisions new nodes to the H/A cluster or notifies the administrator of detected poisoning problem.
