SQL 2014:侦听器和故障转移群集LB [英] SQL 2014: Listener & Failover Cluster LB

问题描述

Reading article on how to set up SQL Availability Group for Azure resources: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sql/virtual-machines-windows-portal-sql-availability-group-overview

创建 2个内部负载均衡器是否正确??
-一个给听众，而
-如果是Windows故障转移群集，则为一个，
>>两个负载均衡器都将指向相同的后端池，这些后端池是SQL Azure VM.

Is it correct that 2 Internal Load Balancers are to be created.?
- One for the listener, AND
- One if for Windows Failover Cluster,
>> Both Load Balancers will be pointing to the same Backend pool which are the SQL Azure VMs.?

-负载均衡器的SKU是否有要求?可以将两个LB创建为基本LB吗?

- Is there a requirement on the SKU of the Load Balancers? Can the two LB be created as Basic LB?

谢谢

推荐答案

仅将创建/需要一个LB. 

Only a single LB will be created/ needed. 

本质上，所有流量都通过具有多个侦听器设置的单个负载均衡器进行.当侦听器发现某个端点处于关闭状态时，它将自动将流量路由离开该端点，并将其定向到正在侦听的端点. 一旦没有响应的侦听器重新联机，则LB将看到此消息，然后开始将流量路由回实例. 

Essentially, you have all traffic going through the single load balancer which has multiple listeners setup. When a listen sees that an endpoint is down it will automatically route traffic away from that endpoint and direct it to the endpoints that are listening. Once the listener that is not responding comes back online the LB will see this and then will start routing traffic back to the instances.
