Cloud computing has several service and deployment models. The service models include the provision of infrastructure, computing platforms, and software as a service. The deployment models relate to how the cloud service is provided. They include a private cloud, operated solely for an organization; a community cloud, shared by several organizations; a public cloud, available to any paying customer; and a hybrid cloud, a composite of deployment models.

Government information technology is subject to a variety of rules, regulations, and procurement policies. Computing is treated differently depending on whether the platform is based on desktops, laptops, mobile devices, or remote file servers known as cloud computing. There are differences between the executive, legislative, and judicial branches of government, as well as in the level of privacy and security expected for various applications.
