Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

SaaS, or Software as a Service, portrays any cloud administration where buyers have the capacity to get to software/programming applications over the web.

A cloud based service is basically just a system that shares information over the Internet, instead of on your hard drive (which would be your local drive and you would not need internet access to use it, but it is only accessible through your computer). The information that you store in “the cloud” is really sent over the internet, and stored on a server with a bunch of other people’s information that the cloud provider owns. Another way to think about it, is that you are basically just “renting” a piece of the cloud service provider’s server to use. Cloud services are so convenient because they allow you to work on your information from any of your devices, just by sending it over the internet, saving it on the provider’s server, and then when you want to access it again from a different device, you simply retrieve it through the internet. “Research shows that the global market for cloud computing will grow from $40.7 billion in 2011 to more than $241 billion in 2020.” (Symantec)
