An Analytical Evaluation of Cloud Computing Service model IaaS & PaaS using Market Prospective

The Cloud sights an important assistance in internet computing. Which provide service in whole world- anything from anywhere. Nowadays, one of the most demandable technique is cloud computing which is not only useful for organization or IT industry but also beneficial for other computer users. Cloud computing is just not only for storage of data but it is much more than that such as it provide services, access to different applications/softwares and many more. Most of the IT companies depend upon it as it is easy to scale up and down. The best part of cloud computing is that it is pay-per-use service through its providers. Mainly cloud computing has three service models i.e. Infrastructure-as-a-Service, Platform-as-a-Service, Software-as-a-Service through which it gives all its usage facilities to its users with the help of high speed network connection. In this paper, the study of cloud computing is presented along with analytical comparative assessment of the two main service model i.e. IaaS and PaaS is carried out deprived of various parameters along with the description of all three models.
