I've got a client with about 40 users that has a few old Windows Server 2008 machines that need replacing. The plan is to replace with an ESXi machine hosting 3 VMs (Domain Controller/File Server, Backup Domain Controller, Application Server). Nothing fancy going on with this client. Their needs are very straight forward.
I'm very familiar with ESXi and completely inexperienced with Hyper-V. I'm extremely versed in Windows Server 2008, but am just getting to know Server 2012.
I'm trying to decide on whether to install 2008R2 servers or 2012R2. I've done a good bit of reading on the differences between 2008r2 and 20012r2. It seems to me most of the advantages are best suited for Hyper-V environments and larger businesses with a significant amount of servers.
With Microsoft's extended support for 2008 ending in 2020, I'm not worried about not having support. I'm not worried about the end of mainstream support in 2015.
Is there any reason why I should install 2012r2 over 2008r2 in a non Hyper-V small business environment without any crazy IT needs?
Look forward to your input.
