Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a cloud computing service model where users provision, instantiate, run and manage a modular bundle of a computing platform and applications, without the complexity of building and maintaining the infrastructure associated with developing and launching application(s), and to allow developers ...
Comparison of on-premise, IaaS, PaaS, and SaaS Cloud computing service models arranged as layers in a stack The National Institute of Standards and Technology recognized three cloud service models in 2011: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Comparison of on-premise, IaaS, PaaS, and SaaS. Infrastructure as a service (IaaS) is the most basic form of cloud computing, where infrastructure resources—such as physical computers—are not owned by the user but instead leased from a cloud provider. As a result, infrastructure resources can be increased rapidly, instead of waiting weeks ...
IaaS services are typically billed as a utility: cost reflects the amount of resources allocated or consumed. Typically, IaaS involves the use of a cloud orchestration technology such as OpenStack, Apache CloudStack, or OpenNebula. It manages the creation of a virtual machine (VM) and decides on the hypervisor (i.e. physical host) in order to ...

Consistency principle: The company uses the same accounting principles and methods from period to period. Conservatism principle : When choosing between two solutions, the one which has the less favorable outcome is the solution which should be chosen (see convention of conservatism )

According to The NIST Definition of Cloud Computing, [3] there are three service models associated with cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The concept of ITaaS as an operating model is not limited to or dependent on cloud computing.
