Techniques are provided for providing computing resources from a pool a plurality of networked computing systems to a consumer. The method includes determining that the consumer's resource usage exceeds a predetermined threshold. After a predetermined period of time, and upon determining that the consumer's resource usage continues to exceed the predetermined threshold, the method identifies one or more computing systems from the pool having capacity to host at least part of the amount of excess resource usage. The method further includes allocating resources on one or more computing systems selected from the identified computing systems to satisfy the amount of excess resource usage, and transferring at least the amount of excess resource usage to the selected one or more computing systems.

Management of unreturned system pool resources

Workload, preferably as one or more partitions, is migrated from a source server to one or more target servers by computing a respective projected performance optimization for each candidate partition and target, the optimization being dependent on a projected processor-memory affinity resulting from migrating candidate workload to the candidate target, and selecting a target to receive a workload accordingly. A target may be pre-configured to receive a workload being migrated to it by altering the configuration parameters of at least one workload currently executing on the target according to the projected performance optimization.

A cloud capacity on demand manager manages capacity on demand for servers in a server cloud. The cloud capacity on demand manager may borrow capacity from one or more servers and lend the capacity borrowed from one server to a different server in the server cloud. When the server cloud is no longer intact, capacity borrowed from servers no longer in the server cloud is disabled, and servers no longer in the server cloud reclaim capacity that was lent to the server cloud.

Managing capacity on demand in a server cloud

In an embodiment, a request is received that requests to move a first partition from a source computer to a destination computer. In response to the request, charging is halted for a resource used by the first partition at the source computer while the first partition is executing at the source computer. In response to the request, a resource is allocated to a second partition at the destination computer. In response to the request, use of the resource is charged at the destination computer. In response to the request, execution of the second partition is started at the destination computer.
