Cost-cutting tips?
What are your favourite, or least favourite but necessary, cost-cutting methods?
I feel I am spending too many resources on unnecessary stuff.
Edit: I feel the need to reduce both – the resources, to host multiple things on one system, and cost, to buy/pay for multiple systems. Currently, I have 2 ARM VPSes and 1 old MacBook Air as a home server.

I see the question has been understood in two ways: cost in computer resources and money. Which one did you mean?
That's the same thing. :) If you reduce computing load, you reduce the need for costly hardware and you reduce the need for energy, thus you reduce the amount of money needed to build and run your setup. There's a saying in (software) engineering : "reducing energy consumption and increasing performances requires the same optimizations". Make your code faster (by itself, not by buffing up hardware) and it consumes less energy. Make your application simpler, and it will run faster, and it will consume less energy. It's not an absolute truth (it sometimes happen that you make your code faster and it consumes more energy), but it's true most of the time.
I guess that's true and I didn't think of it that way. I took it as buying one device over the other to run multiple vms in one machine vs running them in multiple single machines. I'm in that head space now as I'm playing that optimization game myself.
Both!
