链接两个独立的系统或者软件，即使他们有着不同的接口，但是通过中间件都仍能实现信息交换.
常见的中间件有：Tomcat/JBoss(web服务器)/Kfaka/Redis/influxdb/zookeeper/RabbitMQ

lvs的三种工作模式，dr直接路由模式，tun隧道模式，nat模式

- nat: 客户端发送数据包到lvs负载均衡器，在负载均衡器上将数据包的目的ip换为后端rs的ip，rs接受数据包并作出相应将返回的数据包发送给负载均衡器，负载均衡器将SIP替换成自己的ip，最后将响应的数据包发送给客户端

优点是：集群中的物理服务器可以使用任何支持TCP/IP操作系统，只有负载均衡器需要一个合法的IP地址。

缺点：扩展性有限。当服务器节点（普通PC服务器）增长过多时,负载均衡器将成为整个系统的瓶颈。
