Cloud Computing providers offer their services according to different models that forms a layer within a stack.

This system allows the company to reduce IT operational cost and simplify maintenance and support. It is most suitable for the end users who do not possess advanced IT skills. Few applications that use this model are CRM, Email, virtual desktop, communication and games.
Platform as a Service (PaaS )
As it is said on its name, PaaS vendors provide the platform for their Cloud users. Typically, the provided platforms are ranging from operating system, execution runtime, database, web server and development tools. Similar to SaaS, Cloud users with this model do not need to install or manage any hardware. The platform allows the user to build applications and services over the Internet, and Cloud users can simply access the platform via their web browser. This method requires a little bit more skill to operate compare to SaaS.
Infrastructure as a Service (IaaS)
Iaas vendors provide the infrastructure of the Cloud. This model gives more freedom for the users to develop and control the system. Companies who are rapidly growing to be an enterprise usually utilize this model because they are able to scale their Cloud system accordance to their growth. This method is the most complicated out of the three and requires more advance IT skills to operate optimally.
