Nextcloud asked in a poll at https://mastodon.social/@nextcloud@mastodon.xyz/115095096413238457 what database its users are running. Interestingly one fifth replied they don’t know. Should people know better where their data is stored, or is it a good thing everything is running so smoothly people don’t need to know what their software stack is built upon?
I disagree. You are just entertaining the idea that servers must always and forever be oversized, that’s the definition of wasteful (and environmentally irresponsible). Unless you are firing-up and throwing-away services constantly, nothing justifies this and sparing the relatively low effort it is to deploy your infrastructure knowingly.
