In contrast to modern cloud and container solutions based on Linux, even Windows Server Core is large and unwieldy. Microsoft is reacting and has provided the first previews of Nano Server, a further-stripped-down version of Windows Server that drops the GUI stack, 32-bit Win32 support, local logins and remote desktop support, resulting in an on-disk size of about 400MB. The early previews are difficult to work with, and the final solution will be restricted to using the CoreCLR, but for companies that are interested in running .NET-based solutions, Nano Server is definitely worth a look at this stage.
