Abstract

Dynamic consolidation of virtual machines (VMs) can reduce energy consumption by switching idle hosts to sleep mode. However, to meet the quality of service of customers, it is necessary to achieve the trade-off between energy and performance. This paper first puts forward a new dynamic threshold adjustment method using the variation coefficient of historical CPU utilisation, actual CPU utilisation and million instructions per second requests by VMs in migration list. Furthermore, it devises a novel VM allocation policy based on the grey correlation degree model, and formulates a conversion model of CPU utilisation for achieving better trade-off between energy consumption and performance. Finally, some experiments are carried out on the CloudSim and the PlanetLab workloads. The experimental results show that the methods proposed in this paper have obvious advantages on the trade-off between energy and performance during the VM consolidation.

云计算中虚拟机动态整合的能源性能优化

动态整合虚拟机可以将空闲主机切换到休眠模式，从而降低能耗。然而，为了满足客户的服务质量，需要在能源和性能之间实现权衡。本文首先利用历史CPU利用率、实际CPU利用率和迁移列表中虚拟机每秒百万指令请求的变化系数，提出了一种新的动态阈值调整方法。在此基础上，设计了一种基于灰色关联度模型的虚拟机分配策略，并建立了CPU利用率的转换模型，实现了能耗与性能的更好权衡。最后，在CloudSim和PlanetLab工作负载上进行了一些实验。实验结果表明，本文提出的方法在虚拟机整合过程中能量与性能的权衡方面具有明显的优势。

期刊介绍： The advances in distributed computing and networks make it possible to link people, heterogeneous service providers and physically isolated services efficiently and cost-effectively. As the economic dynamics and the complexity of service operations continue to increase, it becomes a critical challenge to leverage information technology in achieving world-class quality and productivity in the production and delivery of physical goods and services. The IJSOI, a fully refereed journal, provides the primary forum for both academic and industry researchers and practitioners to propose and foster discussion on state-of-the-art research and development in the areas of service operations and the role of informatics towards improving their efficiency and competitiveness.
