云服务网关在城市轨道交通中的应用研究

Research on applying cloud service gateway in urban rail transit

为解决城市轨道交通信息系统中传统ESB架构技术相对封闭、扩展性不强、功能模块复用性不高、运维复杂等问题,研究应用开源软件Nginx+OpenResty+Kong作为企业云服务网关,搭建试验环境对其主要功能进行测试;测试表明,该云服务网关配置管理简便、功能插件丰富、水平扩展灵活,有助于降低企业信息系统运维难度和成本,减少不必要的软件开发。

To tackle the problems that the traditional ESB technical architecture used in the information systems of urban rail transit remains relatively closed and complex in operation and maintenance with poor scalability and low reusability of function modules,a study was made on how to apply the open source software Nginx+OpenResty+Kong as urban rail transit enterprise’s cloud service gateway and a lab environment was built to learn its deployment and configuration and to test its main functions.The test results show that the cloud service gateway is horizontally scalable and easy for management and configuration with a wide variety of plug-ins available,which is conducive to reduce the difficulty and cost of operation and maintenance of enterprise information systems and avoid unnecessary software development.
