Multiple Domain controller in on premise

[makhter1982]

Dear Expert,

My company is in Riyadh, Saudi Arabia and we have multiple branches across the kingdom.

Our PDC is in West Europe (Netherlands) and another ADC is in East Europe (Ireland).

and in on premise also we have 6 ADC, which is in my HO and 4 branches.

Is it really required?

Our goal is behind to move our production workload in Azure to reduce the cost and maintenance but still we are in the same.

I am newly join here and as per my understanding it is not required please advise me.

Many thanks in advance.

When you move workloads to Azure you still need to standup 2 Domain controllers AD DS either self or Microsoft managed so that we should Azure VMs can authenticate. Now it would be difficult to say do you need so many ADC maybe they are setup because they you want to authenticate to nearest domain controller
