a layer onto some entity so that the new entity exhibits the
interface properties of the original. This layer hides the true
implementation of the virtualized object so that the original
can be changed or replaced without fundamentally impacting the
interaction of entities that have a dependency on it. An example
is disk LUNs, which present the interface of a disk, yet may be
implemented as a whole disk, a partition of a disk or perhaps an
aggregation such as a RAID stripe. Open Grid Forum - Cite This

using an abstract mechanism so that the underlying physical
resource can be replaced with another one of similar capability
without affecting the resource consumer. Virtualization balances
supply and demand by providing a transparent, aggregated
computing resource. Oracle - Cite This Source - This Definition
