Efficient management of distributive cloud computing system for scientific applications

This paper defines how a distributed cloud computing system is used to define different efficient scientific applications. Generally a distributed cloud computing system is formed from a number of different Infrastructure-as-a-Service (IaaS) clouds which are used in an integrated infrastructure. The production of distributed cloud is continuing since last four years with around 800,000 numbers of completed jobs with an average of about 500 simultaneous and parallel jobs which are executed for about 12 hours per day. Here the design and implementation of system is reviewed based on some custom components and a number of pre-existing components. In this paper the various operations of the system, plans for increasing the computing capacity and expansion to more number of sites is discussed.
