Cloud computing: use cases & various applications

As Cloud Computing has become more and more famous and popular, various Cloud Computing architectures, models and infrastructures have been defined, given their specific circumstances for the applications. Currently, many Cloud definitions, applications and samples can be helpful as a reference for using a Cloud Computing service. As Cloud Computing technology is being used to minimize the cost of computing resources, many enterprises gained interest of migrating their old system to the Cloud Computing system. This further illustrates the importance the usage of Cloud Computing, therefore, this paper investigates some distributed computing model especially cloud computing to clarify which definition, usage, applications and use-cases are more useful. Further, this article attempts to introduce various models of cloud computing, services, use-cases and applications. Finally, we made a comparison between various companies that are providing Cloud Computing facilities. Keywords: Cloud Computing, E-Services, Service Computing, UML, RUP.
