Last month at Microsoft WPC in Toronto, there was lots of buzz about Windows Server 2012. And I’m sure you can tell Unitrends is excited about it too! I came across this great white paper comparing Server 2012 to VMware version, so I thought I’d share some highlights and give you a link to the entire download.
I know VMware is still the big dog in the virtualization space, but we see Microsoft market share growing at exponential rates, and we believe Server 2012 is going to explode this growth.
