DeFiBus(Decentralized Financial Message Bus) -- 分布式金融级消息总线

CI status Coverage Status

       DeFiBus=RPC+MQ,是基于开源消息中间件打造的安全可控的分布式金融级消息总线。DeFiBus不仅提供了RPC同步调用,还提供了MQ的异步事件通知、事件组播和广播等常用服务调用和消息模式,同时增加了应用多中心多活、服务就近、灰度发布等分布式场景下的高可用能力。在对于机器故障的容错能力方面的增强,也让消息总线的服务更加稳定可靠,为业务提供7x24的服务。

分布式架构

architecture1

名词解释 DCN:Data Center Node(数据中心单元化节点)

系统架构

architecture2

DeFiBus主要包括以下几个组件(模块):

  • Broker:通过轻量级的Topic和Queue机制提供消息存储功能。Broker定期将Topic信息上报到NameServer中,同集群中的Broker实例上报的NameServer必须保持一致,避免路由信息不一致。

  • NameServer:NameServer提供Topic的发现和路由,每一个NameServer接受Broker上报的Topic信息,并维护Topic的路由信息供客户端查询。

  • GSL:全局服务定位(Global Service Location)服务提供服务级别的路由发现。服务可以部署在不同的区域(比如不同的数据中心、逻辑分区等),服务请求方在请求某一个具体服务时,无需关注服务部署的区域,GSL能够根据服务发现规则自动定位到具体的服务,将服务信息返回给客户端。

  • EventMesh:服务代理提供TCP/HTTP接入方式,同时允许按照协议规范开发的C、GO、Python等其他语言客户端的接入。

  • ConfigCenter(CC):配置中心,提供HTTP接入方式,比如Namesrv的寻址以及其他配置。

  • ACL:访问控制服务,TOPIC级别的IP访问控制,提供黑白名单功能。

  • SGS:服务治理系统(Service Government System),用于管理服务、服务请求、服务响应、服务路由、ACL等流程和数据。
