一种用于云数据中心的使用在线多资源神经网络的主动自动缩放和节能VM分配框架

Deepika Saxena, Ashutosh Kumar Singh

摘要:

这项工作提出了一个节能的资源供应和分配框架,以满足未来应用程序的动态需求。云用户资源需求的频繁变化导致了过度功耗、资源浪费、性能和服务质量下降的问题。所提出的框架通过精确地将应用程序的预测资源需求与VM的资源容量相匹配来解决这些挑战,从而将整个负载整合到最少数量的节能物理机器上。所提出的工作的三个连续的贡献是:在线多资源前馈神经网络,以预测未来的应用程序的多个资源需求同时;自动缩放的虚拟机的基础上预测的资源需求的聚类;分配的缩放的虚拟机上的节能PM。该集成方法连续优化资源利用率,节省能源,并自动适应未来应用资源需求的变化。建议的框架进行了评估,使用基准谷歌集群数据集的真实工作负载跟踪和不同的场景,包括节能的VM放置与资源预测,VMP没有资源预测和自动缩放,最佳VMP与自动缩放的基础上,实际资源利用率进行比较。观察到的结果表明,所提出的集成方法实现了接近最佳的性能对最佳的VMP和优于其余的VMP在节省功率和资源利用率分别高达88.5%和21.12%。与传统的单输入单输出前馈神经网络预测器相比,OM-FNN预测器具有更高的预测精度、更小的时间和空间复杂度。

英文摘要:

This work proposes an energy-efficient resource provisioning and allocation framework to meet the dynamic demands of future applications. The frequent variations in a cloud user's resource demand lead 'to the problem of excess power consumption, resource wastage, performance, and Quality-of-Service degradation. The proposed framework addresses these challenges by matching the application's predicted resource requirement with the resource capacity of VMs precisely and thereby consolidating the entire load on the minimum number of energy-efficient physical machines. The three consecutive contributions of the proposed work are: Online Multi-Resource Feed-forward Neural Network to forecast the multiple resource demands concurrently for future applications; autoscaling of VMs based on the clustering of the predicted resource requirements; allocation of the scaled VMs on the energy-efficient PMs. The integrated approach successively optimizes resource utilization, saves energy and automatically adapts to the changes in future application resource demand. The proposed framework is evaluated by using real workload traces of the benchmark Google Cluster Dataset and compared against different scenarios including energy-efficient VM placement with resource prediction only, VMP without resource prediction and autoscaling, and optimal VMP with autoscaling based on actual resource utilization. The observed results demonstrate that the proposed integrated approach achieves near-optimal performance against optimal VMP and outperforms rest of the VMPs in terms of power saving and resource utilization up to 88.5% and 21.12% respectively. In addition, the OM-FNN predictor shows better accuracy, lesser time and space complexity over a traditional single-input and single-output feed-forward neural network predictor.
