I wonder which edition StackExchange use?



> I wonder which edition StackExchange use?

Enterprise for the memory and the ability to do online reindexing. They were in the BizSpark program, so they basically got free licensing.


And they are on Software Assurance, right?


Yes, when you exit BizSpark, you can just start paying maintenance on the servers you were using during the program.


I'm fairly certain they use Enterprise because they make use of AlwaysOn Availablility Groups.


Before AGs came out, they used a custom log shipping script for DR, and mirroring for the critical DBs. I don't think they would have gone Enterprise just for the AGs, but since they were on EE anyway, AGs were an easy decision.
