Trust services-oriented multi-objects workflow scheduling model for cloud computing

Abstract

Cloud Computing is promising as a new style of collaborative environment. Efficient Workflow Scheduling is crucial for achieving high performance in Cloud Computing environment. In spite of workflow scheduling has been widely studied. And various algorithms have been proposed to optimize execution time and cost. However the existing cloud services are owned and operated by third-party organizations or enterprises in a closed network. The uncertainty and unreliability existed in the network has caused great threat to the applications. Therefore trust services-oriented strategies must also be considered in workflow scheduling. This paper proposes a Trust services-oriented multi-objectives Workflow Scheduling (TMOWS) model. And a case study has been given to explain the proposed model. © 2013 Springer-Verlag.
