Ubuntu: Server vs Desktop vs Base

Ubuntu is available in : Server, Desktop or Base at:


I do not plan to use it as Desktop, so I am left to decide between server or “base” versions. Given that the server is 2.0GB and the base is 1.1 GB: What exactly does the server provide that base does not? I ask because I plan to setup a Mosquitto MQTT server and a mySQl database to record the data stream.

Download the images and run sudo apt list --installed on both. The server images include a GUI stack for remote access where as the base does not.
