If a cloud provider controls all the hardware aspects of your IT infrastructure, what do you get to control? The answer depends on the type of cloud service model you choose. Cloud service models fall into three categories, all of which are characterized by the term as a service:

 Software as a Service (SaaS)

 Infrastructure as a Service (IaaS)

 Platform as a Service (PaaS)

Many cloud service providers use more descriptive terms in their marketing, including Communications as a Service (CaaS), Anything as a Service (XaaS), Desktop as a Service (DaaS), and Business Process as a Service (BPaaS), to name a few. However, all of these clever names fit into the SaaS, IaaS, or PaaS categories.
