SharePoint 2013 OS: Windows Server 2008 R2 vs Windows Server 2012 Standard
We are thinking on upgrading from SharePoint 2010 to SP 2013 soon. I have been researching about the server OS I should install as host, and it seems that SharePoint 2013 is fully compatible by now with both Windows Server 2008 R2 Standard + SP1 and
Windows Server 2012 Standard. In my opinion we should go with server 2012, but Windows server 2008 is the norm here at our organization and our Infrastructure team seems reluctant to upgrade servers to 2012 yet.
My question is, what SharePoint or Windows 2012 features will we miss if we decide to stay on Windows 2008? What are the perks (selling points) of going with 2012 over 2008? (besides the obvious Microsoft support range extension).
If you stay on Windows Server 2008 R2 you will enter the extended/out of support phase sooner, of course. You will miss out on IIS improvements, although in practical terms it may not mean much.
There are extra patches required for a 2008 R2 deployment that are not needed on 2012 for SharePoint 2013. But other than that, I think the other big issue is that mostly in the community, you'll find people running Server 2012 which means issues are better
'known' by the community, versus 2008 R2 in combination with SharePoint 2013.
