Cloud computing has become a modern paradigm that delivers IT resources as a service over the internet on the pay-per-use basis. Although scientific workflow applications can benefit from resources provided by cloud computing, the challenge is to find scheduling algorithms that can optimise workflow execution. This paper proposes MCT+, an extension to the Minimum Completion Time (MCT) algorithm that can reduce the makespan and cost of workflow execution. We evaluate our algorithm using WorkflowSim and two workflows from the Pegasus workflow management system. Our results show that MCT+ can improve MCT by about 35%.
