SQL Server Standard Always On Availability Groups My environment is running SQL Server Standard. I have 3 instances of SQL Server for the application, the first located at the Head Office, the second at a regional office and the 3rd at the DR site. I plan to implement Basic Always On Availability groups for the application, with the Head office instance as the Primary Replica, the regional office as a Synchronized Secondary Replica, and the DR site as an Asynchronous Secondary Replica. Can this be done? Answer: No Explanation: SQL Server Basic Always On Availability Groups only allow 2 Nodes, viz. the Primary Replica and one Secondary Replica.
