virtualization
All > Technology > Parallel Computing > Grid Computing
- Adding 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 Source - This Definition - Allows interacting with a resource 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.
