Let me see if I read the requirement for Always on Availability Groups correctly with respect to how many nodes per SQL edition. If I want 2 HA nodes (synchronous replica) plus 1 DR node (asynchronous replica), I need Enterprise Edition. If
I only have SQL Std Edn, it can only support 2 nodes (2 HA, or 1 primary node & 1 DR node.) And if Std Edn, it has to be "Basic Availability Group" which can contain only 1 database. Basic Availability groups is only in 2016/2017.
2014 Std Edn does not allow Availability Groups at all. Am I correct on that? Is Basic Availability Groups crippled in any way other than only hosting a single database? Thanks.
