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 here ). 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!
