摘要： 针对OpenStack云平台虚拟机未能较好利用宿主物理机资源的问题,结合基于组件工作的OpenStack在云平台管理中的高效性和Docker容器虚拟化的快速部署优势,搭建基于Docker容器技术的OpenStack云平台。对云平台管理的Docker容器中实际运行的客户机操作系统进行计算、调度、内存访问、文件读写等基础性能测试,做出相关性能的评估与分析,并在多实例运行状态下将其与OpenStack传统虚拟机进行性能比较。分析结果表明,该云平台能够利用Docker容器的轻量级虚拟化优势,优化云计算管理系统的计算性能和文件读写性能。

Abstract: Aiming at the problem that the virtual machines of OpenStack cloud platforms fail to better utilize host physical machine resources,this paper builds a OpenStack platform based on Docker container technology which combines the efficiency of OpenStack based on component work in cloud platform management and the rapid deployment of Docker container virtualization.It tests the basic performance of the guest OSs of Docker container in the cloud platform,including computing,scheduling,memory access and I/O performance,evaluates and analyzes the related performance and compares its performance with the traditional OpenStack virtual machine in a multi instance running state.Analysis result shows that the new cloud platform can optimize the computation performance and the file system I/O performance from a global perspective by using the lightweight virtualization capabilities of Docker container.
