hmark.html 易用性 易用性也是用户比较关注的⼀块内容。产品虽然可以在功能特性或者性能上做到非常先进，但是如 果用户的使用成本极高，也会让用户望而却步。易用性包括多方面的工作，例如 API 和客户端的接 入是否简单，文档是否齐全易懂，控制台界面是否完善等。对于开源产品来说，还有⼀块是社区是 否活跃。在比较 Nacos、Eureka 和 Zookeeper 在易用性上的表现时，我们诚邀社区的用户进行全 Eureka、Zookeeper 的使用场景是有限的。从 我们使用的经验和调研来看，Zookeeper 的易用性是比较差的，Zookeeper 的客户端使用比较复杂， 没有针对服务发现的模型设计以及相应的 API 封装，需要依赖方自己处理。对多语言的支持也不太 好，同时没有比较好用的控制台进行运维管理。 Nacos 架构 < 76 Eureka 和 Nacos 相比较 Zookeeper 而言，已经改 多年双十⼀考验，经历过多次断网，节点全挂，存储不可用各种故障，因此充分面 对失败设计，沉淀了非常多的经验。 全局高可用 Nacos 部署架构上是单 Region 封闭，Region 间独立，跨 Region 通过网关或者 Nacos-sync 完 成服务互通。从而降低 Region 间网络故障风险。 当然用户也可以跨 Region 组 Nacos 集群，但是这样会带来服务跨 Region 互调，真正发生网络

Understanding the space. Let's take a brief look at these: JMS is part of Oracle's JEE specification. It's a Java API that encapsulates both message queue and publish-subscribe messaging patterns. JMS is a lowest common very popular API and is implemented by most messaging systems. JMS is only available to clients running Java. JMS does not define a standard wire format - it only defines a programmatic API so JMS clients
