DEFINITION: "Cloud computing involves in delivering IT as a service. There are 3 major types of cloud computing – Software as a Service (SaaS,) Platform as a Service (PaaS,) and Infrastructure as a Service (IaaS.) While many cloud vendors are focusing in one or two types of the cloud, some companies are offering all three."
The three major types of cloud computing are Software as a service (Saas), Infrastructure as a Service (IaaS) and Platform as a service (PaaS); and now Testing as a Service (TaaS) is a new evolved fourth category of cloud testing.
