I need some assistance in the following...
1) I would like understand how the replication across Availability replicas happen?
does it use Log shipping internally for asynchronous replicas? Log shipping needs
a network share access to the replicas, but I don't think Availability groups require
that, is that right? If so how the data transfer happens across replicas?
2) Can a storage vendor who has storage replication can contribute to AG replication?
