I am installing SQL Server 2016 by using virtual accounts (which I suppose is managed local accounts) and I cannot see any limitation, drawback of using this simpler method vs. using MSAs.
Would a more experience DBA educate us?
My understanding is that: as long as you do not have any cross-server operations, you are fine. I will not cross servers, but I will cross SQL SERVER INSTANCES (on the same server). Are there any issues that I may face?
I've read these resources and another similar question.
