I am having two Windows clusters. Two SQL cluster instances are there in each two node cluster (
Data centre 1 :Windows Cluster 1-SQL2016CLUS1
SQL 2016 failover cluster instance1 -SQL2016DB01
SQL 2017 failover cluster instance2 -SQL2017DB01
Data Centre 2: windows cluster 2-SQL2016CLuS2
SQL 2016 failover cluster instance1 -SQL2016DB02
SQL 2017 failover cluster instance2 -SQL2017DB02
Now I want to configure “Availability Groups” between two SQL 2016 cluster instances(SQL2016DB01 & SQL2016DB02)
How to configure it?
For configuring “Distrubuted Always On Availability groups” We need to create AOAG right(with in same data centre)? How to create AOAG, because i have only one instance
You can try a “distributed availability group”:
A distributed availability group is a special type of availability group that spans two separate availability groups. The availability groups that participate in a distributed availability group do not need to be in the same location. They can be physical, virtual, on-premises, in the public cloud, or anywhere that supports an availability group deployment. This includes cross-domain and even cross-platform – such as between an availability group hosted on Linux and one hosted on Windows. As long as two availability groups can communicate, you can configure a distributed availability group with them.
