When managing your resources, you should be aware of what your goals are.

In addition to resolving resource overcommitment, resource management can help you accomplish the following:

Performance Isolation—prevent virtual machines from monopolizing resources and guarantee predictable service rates.

Efficient Utilization—exploit undercommitted resources and overcommit with graceful degradation.

Easy Administration—control the relative importance of virtual machines, provide flexible dynamic partitioning, and meet absolute service-level agreements.
