Cloud as a Service

A cloud services various types of services that are made available to users on demand via the Internet from a cloud computing servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider. Cloud-computing providers offer their "services" in three standard models. They are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These models offer increasing remoteness; they are thus often portrayed as layers in a stack infrastructure, platform and software as a service, but these need not be related.
