"At its simplest, a data center is a physical facility that organizations use to house their critical applications and data".
A data center's design is based on a network of computing and storage resources that enable the delivery of shared applications and data."

Factors such as Power, Cooling, Monitoring and Related Environmental cost centers (and the capabilities of Cloud Computing) create additional support for downsizing, consolidating or decommissioning all together.
