城轨云架构下灾备方案研究

城轨云架构下,业务集中部署,资源可全面共享与整合。结合云计算技术特性,统筹目前城轨各业务系统应用现状,充分考虑建设成本和各业务系统功能需求、容灾的业务强相关性,旨在探索以实现底层存储双活、数据库双活、网络双活,甚至在实现计算层双活、应用双活的基础上,统筹考虑城轨云承载各业务系统应用的具体情况,制定适应本地基础的容灾架构与方案。以期通过对城轨云架构下灾备方案的研究,为城轨云容灾建设的科学性、可行性提供一定的借鉴。

The Disaster Preparedness Scheme under the Urban Rail Cloud Architecture

In the urban rail cloud infrastructure, services are centrally deployed and resources can be fully shared and integrated. Based on the technical characteristics of cloud computing, this paper plans the application status of the service systems in the urban rail, fully considers the construction cost, functional requirements of these service systems, and the strong correlation of disaster recovery services. This paper aims to explore the ways to realize the dual running of the bottom-level storage, databases, and networks, even to the dual running of the computing and application layers considers the properties of the service system application carried by the urban rail cloud and then plans and designs the disaster recovery architectures and schemes that are suitable for the local infrastructure. It is hoped that the research on the disaster recovery is beneficial to constructing scientific and feasible disaster recovery scheme in urban rail cloud infrasctructure
