Footprint
For example, let's take ready-made Windows Server images that we prepared as in this and look at resource consumption. The size of the page file depends on the amount of RAM installed, so for this comparison it was removed to understand how much the system itself takes up.
Such a small volume was achieved thanks to the manipulations that we have listed in this .
Disk:
Now RAM consumption:
Windows Server 2019 GUI
Windows Server 2019 Core
Windows Server 2019 CORE with Feature on Demand installed, we discussed how to install it in time.
Notes from my own experience
As for real work in a combat environment, for more than half a year of operation and, attention, regular monthly updates, the operating system was rebooted only once, while during the same period Windows Server 2019 with GUI was rebooted every month.
The only reboot was needed because of the .net 4.7 updates, if you don't want to reboot again, just remove unnecessary components.
