We have a forest root domain with 1 domain (we used to have 2 but we just decommissioned a domain). In this domain we have 3 sites containing DCs and we are getting ready to implement our first Azure cloud DC. I am looking for some advice on this.
The current 3 sites containing DCs contain both root and child domain DCs. One of them is our DR site. The other 2 are our main corporate HQ and our off site datacenter. We have 1 forest trust with an offshore partner configured at the forest level.
We soon plan to spin up a DC in Azure for our domain. Is there any reason that I need to also spin up a forest root DC there? Would we do this because of forest trusts? Should someone do that for uniformity? Cost is a factor.
Thanks in advance!
