This has so many variables that it's practically useless as a data point. We have a few Ubuntu VMs running complex business web applications and their Postgres database on only 4 GB or RAM and 20-50 GB of storage, no swap space. Ocassional high load, but Zero OOM problems for many years.
We could upgrade the RAM, but we were stingy when we created them, and it has worked well so far, so why waste resources? Incidentally, using no swap was a deliberate choice, as it would slow things down too much. We preferred to see and correct any memory/OOM issues beforehand, but fortunately we had none.
True. It's just a tiny Lenovo that I've repurposed as a homelab and that is punching above it's weight with to many applications I suppose. Either way the logs point to RAM issues but it could be my incompetence.
