Abstract: Cloud computing is becoming popular in the field of IT industry these days. It’s a model that allows people all over the world to connect to shared pools of programmable resources over the internet. That is, it can execute many apps or programs on many computers at the same time. Cloud computing's nature and applications are continually evolving, both virtually and in reality.The deployment of cloud models is explored in this study.The main cloud deployment types are public,private,community and hybrid clouds. Each of these models has its own set of benefits and drawbacks.Cloud computing is successful in providing a cost effective strategy for most of the companies to manage IT. The major thing that is limiting the cloud’s expansion is security.In this paper different deployment approaches are proposed depending on various security concerns.. Each model adds to the security measures offered by the preceding ones. The last model alleviates security problems.It can be used as a template for future models.
