IT as a service is an operational model where the IT organization of an enterprise is run much like business, acting and operating as an internal service provider. In this model, IT simplifies and encourages service consumption, provides improved financial transparency for IT services, and partners more closely with lines of business. This type of IT transformation is business focused rather than cost focused, leading directly to improved levels of business agility. Typically, ITaaS is enabled by technology models such as infrastructure as a service, platform as a service, all part of cloud computing. ITaaS is core to competitive IT. Lines of business have many options for IT services because public clouds and service providers also offer attractive options. Corporate IT must compete or it will lose relevance. Thus, ITaaS and cloud infrastructure are accelerating IT’s transition to an internal service provider model. Wikipedia [ - ]
