Dubbo出现的目的是为了应对现在高并发，高数据量请求的问题。目前的垂直应用架构已经无法满足现在大数据的冲击，SOA就应运而生，而Dubbo在国内使用的还是比较多，稳定性也比较不错。
架构
节点角色说明：
Provider: 暴露服务的服务提供方。
Consumer: 调用远程服务的服务消费方。
Registry: 服务注册与发现的注册中心。
Monitor: 统计服务的调用次调和调用时间的监控中心。
Container: 服务运行容器。
调用关系说明：
服务容器负责启动，加载，运行服务提供者。 服务提供者在启动时，向注册中心注册自己提供的服务。 服务消费者在启动时，向注册中心订阅自己所需的服务。 注册中心返回服务提供者地址列表给消费者，如果有变更，注册中心将基于长连接推送变更数据给消费者。 服务消费者，从提供者地址列表中，基于软负载均衡算法，选一台提供者进行调用，如果调用失败，再选另一台调用。 服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心。(1) 连通性：
注册中心负责服务地址的注册与查找，相当于目录服务，服务提供者和消费者只在启动时与注册中心交互，注册中心不转发请求，压力较小
监控中心负责统计各服务调用次数，调用时间等，统计先在内存汇总后每分钟一次发送到监控中心服务器，并以报表展示
服务提供者向注册中心注册其提供的服务，并汇报调用时间到监控中心，此时间不包含网络开销
服务消费者向注册中心获取服务提供者地址列表，并根据负载算法直接调用提供者，同时汇报调用时间到监控中心，此时间包含网络开销
注册中心，服务提供者，服务消费者三者之间均为长连接，监控中心除外
注册中心通过长连接感知服务提供者的存在，服务提供者宕机，注册中心将立即推送事件通知消费者
注册中心和监控中心全部宕机，不影响已运行的提供者和消费者，消费者在本地缓存了提供者列表
注册中心和监控中心都是可选的，服务消费者可以直连服务提供者
(2) 健状性：
监控中心宕掉不影响使用，只是丢失部分采样数据
数据库宕掉后，注册中心仍能通过缓存提供服务列表查询，但不能注册新服务
注册中心对等集群，任意一台宕掉后，将自动切换到另一台
注册中心全部宕掉后，服务提供者和服务消费者仍能通过本地缓存通讯
服务提供者无状态，任意一台宕掉后，不影响使用
服务提供者全部宕掉后，服务消费者应用将无法使用，并无限次重连等待服务提供者恢复
(3) 伸缩性：
注册中心为对等集群，可动态增加机器部署实例，所有客户端将自动发现新的注册中心
服务提供者无状态，可动态增加机器部署实例，注册中心将推送新的服务提供者信息给消费者
(4) 升级性：
当服务集群规模进一步扩大，带动IT治理结构进一步升级，需要实现动态部署，进行流动计算，现有分布式服务架构不会带来阻力：
可以得出，注册中心若宕机，只要没有注册新的服务，服务提供者和消费者还是可以根据本地缓存进行沟通。
并且注册中心不是请求转发中心，所以压力是比较小的。搭建Dubbo工程
1、ZooKeeper的配置安装
2、Dubbo-admin配置安装
3、工程API工程创建
工程使用Maven+SpringMVC的方式构建

运行zookeeper，双击zkServer.cmd
运行dubbo-admin，双击Tomcat7w.exe，点击start
在eclipse中用tomcat运行服务提供者，可能存在超时，配置tomcat的timeout配置就可以了
在eclipse中用tomcat运行服务消费者
消费者工程的ConsumerServiceTest下，右键
就可以查看是否成功
正常结果：
gege
