Today, Microsoft announced that Technical Preview 3 (TP3) is available for download for both Windows Server 2016 and System Center 2016. Full details on what’s new in TP3 is defined at, http://blogs.technet.com/b/server-cloud/archive/2015/08/19/what-s-new-in-windows-server-2016-and-system-center-2016-technical-preview-3.aspx.
One of the big new features in TP3 is the introduction of Windows Server Containers, which is very exciting, and very much worth understanding. To that end, I recommend a great blog post published today by Aidan Finn which clearly describes what containers are and how they work, http://www.aidanfinn.com/2015/08/introducing-windows-server-containers/.
Everything else new and exciting you can find described in the top link above, or by getting it installed and getting your hands dirty. 🙂
