IT as a service is an operational model where the information technology (IT) service provider delivers an information technology service to a business. The IT service provider can be an internal IT organization or an external IT services company. The recipients of ITaaS can be a line of business (LOB) organization within an enterprise or a small and medium business (SMB). The information technology is typically delivered as a managed service with a clear IT services catalog and pricing associated with each of the catalog items. At its core, ITaaS is a competitive business model where businesses have many options for IT services and the internal IT organization has to compete against those other external options in order to be the selected IT service provider to the business. Options for providers other than the internal IT organization may include IT outsourcing companies and public cloud providers.
