Abstract

Using cloud computing to execute software processes brings several benefits to software development. Ina previous work, we proposed a reference architecture, which treats software processes as workflows anduses cloud computing to execute them. Scheduling the execution in the cloud impacts the execution cost andthe cloud resources utilization. Existing workflow scheduling algorithms target business and scientific (data-driven)workflows, but not software processes workflows. In this paper, we adapt three scheduling algorithmsfor our architecture and propose a fourth one; the Proportional Adaptive Task Schedule algorithm. We evaluatethe algorithms in terms of their execution cost, makespan and cloud resource utilization. Our results show thatour proposed algorithm saves between 19.74% and 45.78% of the execution cost and provides the best resource(virtual machine) utilization compared to the adapted algorithms while providing the second best makespan.
