Is it possible to configure Always On between two SQL 2016 between two different data centers
Data center 1
Server A --->SQL standalone Instance1
Server B --->SQL standalone Instance2
Data center 2
Server C --->SQL standalone Instance3
Server D --->SQL standalone Instance4
two subnets are used for two data centers
Is Always on possible between these data centers? and also automatic failover
How many Listener we need to create?
