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 ...

On-premises software is sometimes referred to as "shrinkwrap" software, and off-premises software is commonly called "software as a service" ("SaaS") or "cloud computing". The software consists of database and modules that are combined to particularly serve the unique needs of the large organizations regarding the automation of corporate-wide ...
SaaS is scalable, and system administrators may load the applications on several servers. In the past, each customer would purchase and load their own copy of the application to each of their own servers, but with the SaaS the customer can access the application without installing the software locally. SaaS typically involves a monthly or ...
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 ...
