摘　　要：云计算中的服务调度与资源调度对云计算的性能有重要影响,在分析现有云计算调度模式的基础上,针对云计算数据密集与计算密集的特点,提出分层调度策略以实现云计算中的服务与资源调度。分层调度策略对任务进行划分确定作业优先级,并通过数据局部性和总任务完成率对资源进行分配。数值评价部分应用分层调度与已有调度进行比较。实验结果表明,所采用的调度有效提高了资源利用率,为云服务的进一步研究提供了思路。The service scheduling and resource allocation in cloud environment have a major impact on the whole performance of computing. Following the scheduling model in cloud environment, based on cloud computing with data-intensive and compute-intensive features, this paper proposed a stratified scheduling strategy to achieve service scheduling and resource allocation in cloud computing. Through this stratified scheduling model ,the job priority could be decided by service level and task level. And it allocated the resources by data locality and task completion rate. Compared with existing scheduling methods, this stratified scheduling model shows a better performance, and effectively improving the resource utilization. The scheduling modelprovides effective ideas for further research of cloud service.
