Most companies, throughout the years, have believed that the best way to rebalance the economics in the data center is to enable and deliver IT as a Service (ITaaS).  If IT can move from its current methodology of addressing business needs with dedicated IT infrastructure to addressing them via more efficient, automated on-demand services, IT offerings can be more consistent, timely, and more responsive to business needs.  In the past, the technology wasn’t really there to enable that.  Now, capabilities such as virtualization and cloud can help customers deliver these services rapidly.

Many organizations are overcoming inflexibility in the data center by building a virtualized private cloud to support workloads such as collaboration, web serving, batch processing, or test and development environments. Cloud computing uses shared pools of virtualized infrastructure resources and a highly network-centric operating model to enable fast provisioning and improve performance. Platforms such as Cisco UCS brings together high-performance networking with compute, storage, virtualization, and management resources into a unified platform that provides an exceptional foundation for cloud.

This vision should give organizations the flexibility to deliver these services in house via a private data center or private cloud, as well as giving IT the option to leverage  external services as well via software as a service,  external public cloud services, or an integrated solution.
