Windows Server 2016 Standard
The Standard edition is ideal for customers with low density or non-virtualized environments.
All physical cores on the server must be licensed, subject to a minimum of 8 core licenses per physical processor and a minimum of 16 core licenses per server.
CALs are required for every user or device accessing a server.
Standard edition permits use of one running instance of the server software in the physical OSE on the licensed server (in addition to two virtual OSEs), if the physical OSE is used solely to host and manage the virtual OSEs.
While no features from the Windows Server 2012 R2 Standard edition have been removed, we have added features like Nano Server and unlimited Windows Server containers to the Windows Server 2016 Standard edition.
