Review on Modeling and Implementation of Cloud Computing

Abstract — Cloud computing is an emerging technology. Advances in virtualization, storage, connectivity and processing power are combined to create a new ecosystem for cloud computing. In this paper the concepts of Cloud Computing like type of cloud, cloud deployment models, advantages of using cloud and risks involved in it are analysed. This paper tries to bring awareness among managers and computing professionals to use Cloud computing as an alternative to large in-house data centres. The current approaches to enabling real-time, dynamic infrastructure are inadequate, expensive and not scalable to support consumer mass-market requirements. Over time, the server-centric infrastructure management systems have evolved to become a complex tangle of layered systems designed to automate systems administration functions that are knowledge and labour intensive. This expensive and non-real time paradigm is ill suited for a world where customers are demanding communication, collaboration and commerce at the speed of light. Thanks to hardware assisted virtualization, and the resulting decoupling of infrastructure and application management, it is now possible to provide dynamic visibility and control of services management to meet the rapidly growing demand for cloud-based services
