Installed a Windows Server 2019 Essentials server into a new client about 2 weeks ago. Their current infrastructure consisting of way too many servers is completely borked and there's no way I want to bring any of that mess over to the new setup. I've got a concurrent setup running alongside right now, with their main file server connected via secondary NIC into the new infrastructure using new IP schema and copying over their entire shared document library.
My question is in regards to Active Directory/Domain controller setup, etc. I'm fine with using Azure AD services, if that's a viable setup with this new system. They're already on Office 365/Azure basics and would be OK with setting them up on premium Azure AD if an option is to keep the on premise server strictly as a member <file> server and force everyone to authenticate via the cloud.
Or, is it the consensus of the group to maintain a DC on premise and setup a hybrid connection with the cloud.
Thanks in advance for your thoughts and comments.
