Run whatever you like!

I personally enjoy the big machines (I've also always enjoyed meaninglessly large benchmark numbers on gaming hardware) and enterprise features, redundancy etc. (in other words, over-engineering).

I know others really enjoy playing with K8s, which is its own rabbit hole.

My main goal - apart from the truly useful core services - is to learn something new. Sometimes it's applicable to work (I am indeed an SWE larping as a sysadmin, as another commenter called out :-) ), sometimes it's not.
