关于民航领域集成系统可持续迭代的架构设想

【摘要】 长期扩展性系统具有独立模块成型快、系统发展时间长、模块迭代频繁的特点。因此将独立模块服务化、采用可插拔的服务注册机制并通过完善的权限控制和认证实现新旧服务之间的通讯,进而在提高数据和服务的复用性避免重复开发的同时保证了每个独立服务的高可用性。分布式系统的CAP理论要求在架构的设计前期对CP和AP作出抉择,而由于民航的领域特性,对于高可用和分区容错性的要求远大于一切,因此以AP为原则的去中心化设计成为首选。更多还原

【Abstract】 The long-term extensibility system has the characteristics of fast independent module forming, long system development time and frequent module iteration. Therefore, the independent module is serviced, the pluggable service registration mechanism is adopted, and the communication between the old and the new services is realized through perfect authority control and authentication.In turn, it can improve the reusability of data and services to avoid repeated development while ensuring the high availability of each independent service. The CAP theory of distributed systems requires a choice between CP and AP in the early stage of architecture design, but because of the domain characteristics of civil aviation, the requirements for high availability and partition fault tolerance are far greater than anything else. Therefore, the decentralized design based on the principle of AP has become the first choice.更多还原
