Windows Server 2012 Datacenter and Standard are technically identical – there is absolutely no difference between them with regard technical capabilities.
The only difference is the virtualisation rights included with the license (two VMs for Standard and as many as you like for Datacenter). So if you’re virtualising you should be using Datacentre – that’s the only decision you have to make. As a rule of thumb, once you get to around five VMs you should have gone with Datacentre.

Good to know. Thank you.
Great Article, simple and to the point, answered everything I wanted to know!
helpful article need more information.
Isn't it once you get to around 9 VM's you should have gone with Datacenter? The standard license (around $850 US) gives you 2 VM's. Datacenter costs around $4500 US for 2 processors. 4 Standard licenses (good for 8 VMs) costs less than 1 Datacenter license . . .
Unless you mean "per processor".
Nice article . . .
