| 摘 要： | 提出了一种基于动态重用的成本感知的云服务请求调度算法, 不仅能够根据当前的系统负载状况和云服务请求的可分性特征,按需租用和重用虚拟资源,实现云服务动态请求的优化调度,而且还能在满足服务等级协议约束的同时,最小化虚拟资源租赁成本,增加云服务供应商的利润. 仿真实验表明,提出的算法的资源利用率、运营利润均高于用以对比的调度算法.

| Abstract: | With help of a new cost-aware cloud service request scheduling algorithm based on dynamic reuse, according to current system load and divisible character of cloud service requests, the virtual resources can be rent and reused on demand to achieve optimal scheduling of dynamic requests in reasonable time.The rental cost of the overall infrastructure for increasing cloud service providers’ profits can be minimized when meeting service level agreement constraints. Simulation indicates that our proposed algorithm shows better performance compared with other revenue-aware algorithms in terms of resource utilization and operation profit. |

| Keywords: | cloud service service level agreement cost-aware virtual machine generic algorithm |
