IntroductionClouds are rapidly becoming an important platform for scientific applications.

Large scale Cloud computing infrastructure are unified computing platform which tries to connect and share all resources in the Internetcomputation resourcestorage resourceInformation resourceknowledge resourceIntroduction (cont.)

15ConclusionThe main contribution of this study to scheduling systems is that it extends the traditional formulation of the scheduling problem so that both execution time and reliability of applications are simultaneously accounted for.

Considering other aspects of security in Cloud environment is our future work.
