I have a Dell R720 on premise that acts as my primary domain controller for workstations. At one point the machine had many more functions and features and it was necessary to keep an on-premise server. However, over the years a lot of services have been moved to the cloud. All this thing is really used for anymore is simple file shares. Granted, these file/folder shares will likely need to continue with restricting access to certain groups or individuals.
But I was wondering. Could this file/folder share service be replaced with an SMB server? Or other simple file/folder sharing service provided by a Raspberry Pi perhaps? Then I can cut down my power consumption significantly.
If so, could I still restrict file/folder access through some sort of user account?
