基于地理信息私有云的同城异地容灾应用研究

Application of Disaster Tolerance in Different Places of the Same City Based on Geographical Information Private Cloud

研究了在已建地理信息私有云平台基础设施上搭建同城异地数据中心的容灾环境,结合待容灾业务应用系统特点分析了两种常规的容灾技术方案;并通过人员易用性、RTO、RPO和可维护性等指标进行对比,提出了适合用户自身实际并可指导后期实施的最优容灾应用解决方案。

In this paper, we studied the disaster tolerant environment of different data centers in the same city building on the infrastructure of private cloud platform of geographical information. Based on the characteristics of the disaster tolerant business application system, we analyzed two kinds of conventional disaster tolerant technology schemes. By comparing the indices of user’s ease of use, RTO, RPO and maintainability, we put forward the optimal disaster tolerance application solutions, which could suit the users, and guide the implementation.
