协议更容易让人理解， 并且有很多成熟的工业算法实现，比如蚂蚁金服的 JRaft、Zookeeper 的 ZAB、Consul 的 Raft、 百度的 braft、Apache Ratis；因为 Nacos 是 Java 技术栈，因此只能在 JRaft、ZAB、Apache Ratis 中选择，但是 ZAB 因为和 Zookeeper 强绑定，再加上希望可以和 Raft 算法库的支持团队 随时沟通交流，因此选择了 列表变化的注册中心产品。 互联网软件行业普遍热捧开源产品，因为开源产品代码透明、可以参与共建、有社区进行交流和学 习，当然更重要的是它们是免费的。个人开发者或者中小型公司往往会将开源产品作为选型首选。 Zookeeper 是⼀款经典的服务注册中心产品（虽然它最初的定位并不在于此），在很长⼀段时间里， 它是国人在提起 RPC 服务注册中心时心里想到的唯⼀选择，这很大程度上与 Dubbo 在中国的普 及程度有关。Consul 服务的实例又会有划分为多个子集的需求，例如⼀个服务是多机房部署的，那么可能需要对每个机 房的实例做不同的配置，这样又需要在服务和实例之间再设定⼀个数据级别。 65 > Nacos 架构 Zookeeper 没有针对服务发现设计数据模型，它的数据是以⼀种更加抽象的树形 K-V 组织的，因 此理论上可以存储任何语义的数据。而 Eureka 或者 Consul 都是做到了实例级别的数据扩展，这
