Windows 8 & Multi-Tenancy AD

So apparently all the new hyped-up multi-tenant features of Windows 8 that Microsoft and all the blogs have been slathering over is all related to Hyper-V and how you can use it to do multi-tenancy (MT). Their version of MT is literally only talking about how you can have multiple VM’s running in Hyper-V and how they can be completely separated on the same box (good article hereĀ ). Apparently it does this by vlan tagging – which I didn’t realize wasn’t already an option in Hyper-V. We’ve been doing this in ESX for years the exact same way.

What this means is that AD is still normal Windows Active Directory. Sure there are some nice, new, bells and whistles, and a whole new, clunky interface, but underneath it’s still the same AD it always was. This makes me sad in this day of “Cloud” and everyone having to have their own public and private cloud, the buzz words like IaaS, SaaS, etc. Still no multi-tenant AD. And for most companies and customers out there who don’t want to build a whole new AD to support a half dozen servers, we’re still back to the old ways of setting custom AD permissions on OU’s and objects. Mark me sad.

To sum up: multi-tenancy in Win 8 is just Hyper-V with vlan-tagging. Stuff we’ve been able to do for years, anyway.

Back to the drawing board for me!

Windows Server “8” Preview

If you’ve read my previous post below – and you ARE following me religiously, right? – then you know that I really don’t like to read the manual (RTFM!). That being said, I recently downloaded the Windows Server “8” beta and tried to throw it up on my ESXi 5.0 servers. And they blue-screened.

Thankfully it had a frowny-face, so at least I felt better about it.

After some googling/digging I discovered that Win Server 8 isn’t really supported on ESX yet. Some people report success, some don’t. Supposedly if you update to 5.0 Patch 2 it might work. Or so the articles say.

Unfortunately for me, I can’t really take downtime right now to really test it. So on to another solution…

VMWare Workstation 8. Supports it like a charm. The key is to NOT specify OS customization during the creation of the VM. Just tell it you’ll install the OS later and then mount the ISO and do your thing.

Of course then you’ve got the problem of sharing resources on your machine with your VM, so hopefully you have a beefy machine (unlike me). I allocated 2 CPU’s and 1 GB of RAM to the VM. It’s a little clunky, but it’s passable.

Stay tuned as I start testing Win 8. I have a few items of interest I’m looking at, but will also give my general comments as I run along things. I’m mainly looking at the new multi-tenancy features of AD, CIFS2 file sharing, and just general interface changes. I’ve never been a fan of Hyper-V, and am not sure I can run it within a VM, but I might look at that, too, since everyone says it’ll do away with Citrix and I happen to love all things Citrix.
