Re: Thanks for the tip
Windows 10 is already very stable - with the latest feature update I would have no issues with deploying it in an enterprise environment, and we are already piloting it.
Windows Server historically has been stable / useable from the point of release with no need to wait for the first update as has sometimes been the case on the desktop! However I wouldn't say that Server 2016 RTM in anyway defined the readiness of Windows 10 - which is already on well over 100 million desktops.
Back on topic - I note loads of integration / functionality / TCO reasons to use Windows Server instead of a zoo of OSS solutions in this release - particularly on hybrid cloud and large datacentre estates. Looks like we can also potentially ditch lots of our legacy load balancing and firewall solutions...
Imagine - a few clicks on a GUI and an Active Directory based SDN or firewall policy can be updated in a few minutes on every firewall / network devices / load balancer with no manual activity required. Like the days of ISA server, but they have gone back to the drawing board and provided a better enterprise class solution. This is what all of Azure already runs on by the way!
