摘要
围绕城市轨道交通云计算平台主要的系统架构和容灾方案讨论,从安全可靠性、实施难度、建设和运营成本、配套设施需求和运维管理等方面详细分析各种方案的优缺点,对城市轨道交通云计算平台组网方案提出一些合理建议。经论证,城市轨道交通云计算平台采用两级架构具有更高的安全可靠性,同时工程实施难度较小。但系统容灾方案需综合考虑外部因素,灵活采用分级混合部署方案,才能最大程度发挥各种方案的优势。
This paper focuses on the main system architecture and disaster recovery scheme of the cloud computing platform for urban rail transit.It provides a detailed analysis of the advantages and disadvantages of various schemes from the aspects of safety and reliability,implementation difficulty,construction and operation cost,supporting facilities requirements as well as operation and maintenance management,and puts forward some reasonable suggestions for the networking scheme of the cloud computing platform for urban rail transit.Verification results show that the cloud computing platform for urban rail transit of two-level architecture features higher safety and reliability and has lower implementation difficulty during actual projects.However,external factors need to be considered for the system disaster recovery scheme,and a hierarchical deployment scheme should be adopted flexibly to maximize the advantages of various schemes.
