Windows Server 2016 is coming soon. While Microsoft has not issued a formal release or launch date yet, the updated server OS is due out sometime in the coming months. As I understand it, we are likely to see one further technical preview before RTM. I’m expecting RTM to be over the summer and expect to be able to download it from MSDN soon after. We’ll see how accurate my guesstimates are – and no I have NO inside information.
A sign that the new OS is coming soon is the release of a new e-book: Introducing Windows Server 2015 Techical Preview. It’s a bit dated (it was released in April) but has great details of the key new features of Server 2016, including Nano Server, Containers and the huge host of other updated or new features. I have downloaded the PFD and have been reading it on my train journeys to/from London.
