发布时间:2018-07-28 18:37
【摘要】:为了保证响应时间百分比SLA的同时,最小化商用云中心资源配置成本,基于排队理论提出了云中心模型,从经济角度分析云中心资源配置成本,并推导出云中心响应时间百分比的数学表达式。给出了计算最小配置成本算法(MPCA),通过大量实验分析了负载流量、响应时间百分比和基准响应时间对配置成本的影响。实验结果表明,通过MPCA对云中心服务器数量和运行速率进行优化,可以使配置成本随着负载流量的增加而呈线性增长。
[Abstract]:In order to ensure the percentage of response time (SLA) and minimize the cost of commercial cloud center resource allocation, a cloud center model based on queuing theory is proposed to analyze the cost of cloud center resource allocation from an economic point of view. The mathematical expression of cloud center response time percentage is derived. The minimum configuration cost algorithm (MPCA),) is presented to analyze the effects of load flow response time percentage and benchmark response time on configuration cost through a large number of experiments. The experimental results show that the configuration cost increases linearly with the increase of load flow by optimizing the number and running rate of cloud central servers by MPCA.
