How to deal with AD when deploy Hyper-V cluster?

us flag

I try to plan Hyper-V cluster deployment over several host servers (10 or maybe 12; hosts are rented) placed in two separate datacenters. This will be Hyper-V Server 2019 Core hosts. The problem is, I don't know if I should rely on AD for host auth, and if not, then what's the best way to maintain the cluster.

The main idea was to create Hyper-V cluster that's not connected to office AD servers so even if office goes down for a long time services in datacenters should stay alive. I have no physical hosts in datacenters to serve AD only, all of these hosts are for Hyper-V, and I don't want to host AD controllers as VMs as it kills the whole idea.

Feel I miss something as I believe this is the question for each and every Hyper-V deplyment on a remote location, so pleace advice best way of how to work this out.

Thank you!

"Feel I miss something" - DOCUMENTATION? Clustering works even without domain now - workgroup - with nearly all features and since 2016. You must have overlooked that.

@TomTom I knew about domainless setup, but I deal with it back in Windows 2012 Hyper-V, so yes, I overlooked that in 2019. What's more interesting, I can't find best practice docs for "Put both AD DCs on Hyper-V and Hyper-V can be maintanced / start without AD and AD will be added at late stage" approach. Seems that it is against AD general approach, isn't it?

What is the logic behind that give nthat "AD servers goes down" is a non issue if 2 of them live on the cluster, AND the cluster since 2019 can live and start without AD?

and I don't want to host AD controllers as VMs as it kills the whole idea.

Nope, it does not. It follows best practices.

rent additional servers for the AD usually 4-8gb at least and 2-4 CPUs should be already overkill

Not really. One, every location should have AD to start with. Second, since - 2 years (2019 version) Clustering works perfectly without AD and ind mixed environments (some machines in AD, some of the servers in a workgroup).

This can be true but that's what I said, rent additional servers for the AD ;) if 2 location at least 1 one each site should be the standard ,better having 2 on each site. However in case you cluster such massive remind also how to backup the entire cluster

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
