Workflow scheduling is most important concerned in a cloud computing environment because it depends on optimization objectives (like makespan, cost, reliability, security, energy consumption and energy cost, load balancing etc.) of scientific applications. In this review paper, we describe various ...
Cost-aware challenges for workflow scheduling approaches in cloud computing environments: Taxonomy and opportunities Alkhanak, E.N., Lee, S.P., Khan, S.U.R.: Cost-aware challenges for workflow scheduling approaches in cloud computing environments: Taxonomy and ... EN Alkhanak,SP Lee,SUR Khan...
Ineffective scheduling of workflows creates challenges for CSP, cloud users by delaying execution of tasks, increase in rate of failures, underutilization of resources. Many earlier authors proposed various workflow scheduling mechanisms with different metaheuristic optimization approaches but generating ...

We describe how the application was deployed, evaluate its performance executing in different clouds (based on Nimbus, Eucalyptus, and EC2), and discuss the challenges of deploying and executing workflows in a cloud environment. We also demonstrate how Pegasus was able to support sky computing by ...
Cloud computingGenetic algorithmHeuristicWorkflow schedulingCloud infrastructures are suitable environments for processing large scientific workflows. Nowadays, new challenges are emerging in the field of optimizing workflows such that it can meet user's service quality requirements. The key to workflow ...
In this paper, we first analyze the gap between these two complementary technologies, and what it means to bring Clouds and workflows together. Then, we present the key challenges in supporting Cloud workflows, and present our reference framework for scientific workflow management in the Cloud. ...
Workflow scheduling is one most difficult task which needs to be looked at in the cloud computing environment. This is due to the complexity in its structure, as one workflow application can produce many discrete tasks for scheduling [14]. This have been defined by many researchers as NP-compl...
