We've successfully extended our on-premises active directory to AWS, creating domain controllers as EC2 micro instances, we loosely based our setup on the Amazon White Paper: Implementing Active Directory Domain Services in the AWS Cloud
We are in the process of implementing a system of stopping all of our EC2 instances outside of business hours and starting them inside of business hours. However, I can't seem to find any documentation regarding the effects (if any) of stopping and starting these DCs along with other EC2 instances.
SatanicPuppy gave a very vague warning on this topic in his answer on Can Amazon VMs be used as Active Directory domain controllers?:
There are all kinds of problems that you can have when you lose access to a domain controller, so any network interruption will have huge business consequences
Jesper Mortensen outlines detailed reasons not to put a DC in AWS in Running Windows domain on Amazon EC2 but this might be several years out of date at this stage
Finally, my question is: If these DCs were powered off for a whole weekend, would this cause problems with the other EC2 instances?
EDIT 1: I'm well aware this might be a difficult question to answer but I won't accept a 'why would you want to do this' or 'just don't do this' type answer. The question is pertaining to the specific problems this would cause, not whether or not it's a good idea
