| Abstract: | Based on the study of existing cloud computing services scheduling algorithm, a QoS- based distributed multi-target service scheduling algorithm was designed and achieved. This algorithm considers the user needs and the overall performance of the system, on the basis of the completion time, cost, overhead and load balancing multiple parameters for service scheduling to obtain better scheduling quality. Experimental results show that the scheduling algorithm not only meets the user＇s QoS requirements of clouds, but also adjusts the load balancing and improves the operating efficiency of cloud computing platform. |
