Data Center Virtualization
Virtualization is changing the landscape of the data center. Consolidation began as a trend toward centralizing all the scattered IT assets of an enterprise for better cost control, operational optimization, and efficiency. Virtualization introduced an abstraction layer between the hardware and the software, allowing enterprises to consolidate even further. Virtualization gets the most out of each physical server platform in the data center by running multiple servers on it.
