I'm reading some windows docs about AOAG and I got confused:
Always On availability groups, the high availability and disaster recovery solution introduced in SQL Server 2012 (11.x), requires Windows Server Failover Clustering (WSFC). Also, though Always On availability groups is not dependent upon SQL Server Failover Clustering, you can use a failover clustering instance (FCI) to host an availability replica for an availability group. It is important to know the role of each clustering technology, and to know what considerations are necessary as you design your Always On availability groups environment.
Windows Server Failover Clustering and Availability Groups Deploying Always On availability groups requires a Windows Server Failover Cluster (WSFC). To be enabled for Always On availability groups, an instance of SQL Server must reside on a WSFC node, and the WSFC and node must be online.
I've never heard about aoag without windows failover cluster.
is it possible to have AOAG on just 2 machines not part oa windows clustering?
