【摘要】：针对现阶段使用私有云评测方法缺失所导致搭建私有云供需不匹配的问题,提出了一种自适应、可扩展的私有云系统能力检测方法,可对基础设施即服务(IaaS)云计算系统能力进行评测。首先,通过私有云应用程序接口动态扩展虚拟机数量;然后,通过性能特征模型选取虚拟机所需配置的硬件信息和操作系统类别,并根据用户的需求差异使用不同的负载模型,形成相应的模拟运行环境;最后,使用云计算服务等级协议(SLA)作为测试标准来衡量私有云服务能力。使用所提方法对Openstack开源私有云平台的能力进行了评测,实验结果表明,所提方法可以准确得出私有云服务能力,结果和用户实测一致。该方法负载生成成本更低,测试效率更高。并将该方法与Openstack自带的组件Rally进行对比,拓展性和负载动态模拟有很大的改进。
[Abstract]:Aiming at the mismatch between supply and demand of private cloud due to the lack of private cloud evaluation method at present, an adaptive and extensible method for detecting the capability of private cloud system is proposed. The capability of infrastructure as a service (IaaS) cloud computing system can be evaluated. Firstly, the number of virtual machines is dynamically extended through the private cloud application program interface. Then, the hardware information and operating system categories of virtual machine are selected through the performance feature model, and different load models are used according to the user's demand difference to form the corresponding simulation running environment. Finally, the private cloud service capability is measured using cloud service level protocol (SLA) as a test standard. The proposed method is used to evaluate the capability of Openstack open source private cloud platform. The experimental results show that the proposed method can accurately obtain the private cloud service capability, and the results are consistent with user measurements. The load generation cost of the method is lower and the test efficiency is higher. The method is compared with the component Rally of Openstack, and the expansibility and load dynamic simulation are greatly improved.
