Although all the three major types of cloud hosting services that are recognized as IaaS, PaaS and SaaS, aim at facilitating the use of cloud computing by a cloud user, the comparison and contrast between them can easilybe drawn because of the individuality of these services.
 
IaaS in Comparison with PaaS and SaaS
Infrastructure as a Service IaaS is a very major development in cloud computing. If we compare this service with the other two services that cloud computing offers, we might be able to conclude that this service is also as multidimensional and effective as the other two. IaaS enables the users to handle the virtual servers in their own way. It means that the users should be able to start and stop their virtual serversas per their requirement, with the help of it. Accessing a virtual server should evenbe easier for the IaaSusers. Another major service which helpsIaaSto be comparedand paired successfully with PaaS and SaasS, is the facility it gives to its users to configure their virtual servers and storage.

The story of cloud hosting solutions does not stop with IaaS, rather it goes on in the form of Platform as a service. As far as the contrast and unity amongPaaS, IaaSand SaaSare concerned,PaaS basically offers software development tools which the cloud service providers host. PaaS alsohelps the developers to create applications on the platform of the service providers. This is a unique feature of this cloud subdivision which clarifies the comparison, especially between thePaaS and theIaaS as the former is all about the availability of proper tools for the creation and development of softwares and the latter is all about the availability of virtual servers online.
 
SaaS in Comparison with IaaS and PaaS
Among the subdivisions of cloud infrastructure as a service, software-as-a-service is quite unique and different from the rest others. The major contrast between the SaaS and the other two dimensions of cloud hosting is that the SaaS is a service that does not necessarily deal with services of virtual servers which is a specialty of IaaS or software tools which is typical attribute of PaaS, rather SaaS is all about working on e-mails and database processing. In SaaS,the end-user should be able to use this service from anywhere and at any time.
