1. A method comprising: determining a set of processors having multiple processor cores present in a computer system, the processor cores forming an aggregated set of processor cores for the system; determining a set of dependencies among a set of workload components executing on the set of processors and processor cores, wherein the aggregated set of processor cores are distributed across multiple processors; receiving a policy, the policy including rules associated with managing one or more of power consumption, heat production, or operating cost for the aggregated set of processor cores; receiving a workload event; and in response to the workload event, migrating one or more applications or services from one or more of the processor cores in the aggregated set of processor cores in accordance with the workload event, the policy and the set of dependencies, wherein the one or more applications or services are migrated from a first set of processor cores on a first set of processors to a same number of processor cores on a second set of processors, wherein a number of processors in the second set of processors is less than a number of processors in the first set of processors.
