A very simple explanation of a data center would be a place where data is stored. Storage, computing and network resources have become 'virtual' and are accessed by a wide range of applications and users.

Whether attuned to consumers or inward-looking, as with an intranet model, whether it is supply chain management system or an e-business portal, a data center requires heavy investments in IT resources and management.
