随着信息技术的发展,传统的并行计算和网格计算等计算模式逐渐发展成为云计算.当前云计算服务应用于各行各业.企业也可以搭建自己的私有云,为内部员工提供更加便捷的服务支持.云服务的可靠性是一个值得讨论的问题.针对OpenStack私有云的高可用性进行分析,将其服务状态分为有状态服务和无状态服务,设计私有云平台各个模块的高可用方案,实现Openstack私有云平台的高可用性.%With the development of information technology, the traditional parallel computing and grid computing model has been gradually developed into cloud computing. The current cloud computing services are used in all walks of life. The enterprises are supported to build their own cloud privately for providing internal employees with high quality and convenient computing service. The reliability question of its service is worth out while disscussing. This paper analyzes the high availability of OpenStack private cloud, divides the service status into stateful and stateless. The paper also de-signs the high availability scheme to each module of private cloud platform, and realizes the high availability of Open-Stack private cloud platform.
