how i dream of buy a few 12 tb drives.
Rotational hard drive prices are up, but not that far, not like RAM, especially if you’re not getting the largest drives possible.

That’s maybe a doubling on 12TB drives from the trough. I mean, sure, it’s significant, but if you were already talking about getting several, you can certainly get one.

Hmm.
A lot of these are going to be just request-driven. That is, they aren’t really doing anything while idling. Thus, they don’t really need to be actually running.
If the idle memory usage is an actual concern — and honestly, the OS is probably just gonna page things out if the software is truly idle and it needs the memory for something else and it has paging space…I kind of assume that someone has built some sort of system that works like inetd, which avoided leaving non-containerized servers running. You register a port, and then inetd listens on it. When someone connects, it starts up the daemon in question (say, Apache or whatever). Just need to start a container on demand here. Maybe close it down after a long-enough period of inactivity.
