SDN is mainstream - Microsoft has their own Linux SDN distro

Microsoft shocked the tech community today when they announced that they are building their own Linux based network OS called Azure Cloud Switch to run their Azure switches.  Microsoft is a member of the Open Compute Project and is a founding member and contributors to the Switch Abstraction Interface standard.  They are not the first large company to move to a Linux SDN stack to run their datacenter switches.  Google and Facebook have been doing this for over a year.

Two weeks ago it was Microsoft on-stage for the keynote at VMworld. Then it was Cortana deeply integrated into Cyanogen.  What's the next surprise from Redmond?
