Till now many parameters considered in QoS driven like makespan, latency and load balancing. But allocation cost parameter is not considered in QoS-driven scheduling algorithm. Minimizing the total allocation cost is an important issue in cloud computing. In this paper, the cost is calculated of QoS-driven task scheduling algorithm and compare with traditional task scheduling algorithm in cloud computing environment. The experimental results based on cloudsim3.0 toolkit with NetBeans IDE8.0 shows that QoS-driven achieves good performance in cost parameter.
