Description:
Improvement
This improvement enables you to create a new type of Availability Group (AG) listener that's named "distributed network name (DNN) listener" without the load balancer. Note Removing the load balancer greatly reduces the configuration complexity and also greatly reduces the AG failover latency (by 6 to 7 times for some workloads).
