The necessity for static overprovisioning is reduced because WebSphere XD is able to dynamically adapt and adjust its behavior, both in request routing and application placement, as the resources allocated to partitions change. Not every application needs to be simultaneously preallocated with the maximum amount of resources that it will need at peak demand, because resources can be dynamically allocated as needs change.
Combining the dynamic resource partitioning available through dynamic logical partitions with the dynamic operations of WebSphere XD enables the data center to be reconfigured through a combination of manual actions and autonomic controllers, as demand and business goals change, without requiring redeployment or static reconfiguration.
