Abstract
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.
Highlights
In this world, it is very necessary to make facility for people that provide possibility for them to contact with together quickly or send messages or different media types of data to each other through Internet or World Wide Web (WWW) facilities [1]

This author made a classification for business models and 8 classes has been proposed for business models of cloud computing
Summary
It is very necessary to make facility for people that provide possibility for them to contact with together quickly or send messages or different media types of data to each other through Internet or World Wide Web (WWW) facilities [1]. Several software-developing companies, which have located in different countries, need to consider the situations and requirements of their users for creating the new E-services These companies attempt to share their knowledge, schedule their various activities or manage strategies for building global systems instead of local systems. Based on these research efforts, Cloud computing is identified as a model which is creating possibilities for on-demand access to shared data in configurable computing memories or resources by the help of Networks or Internet [2]. Another definition of Cloud computing is, saving data or applications of organizations through Internet in distance servers [3].
