Or would it be better to split it up on multiple devices? Or maybe just upgrade to a single RPi4 or 5 mod. B?
You could say that with most any hardware. You could have a dedicated server fail and have your network be down till you got another instance up or have a “fall back” kick in.
What makes Rasp Pi so much more unstable? If anything a couple PIs are definitely a cheaper solution compared to other hardware like you are suggesting?
couple of Pis are cheaper
Are they thou? In my region the 4Bs are selling at around 60 bucks (no case, no SD)… A “couple” of them (including some for backup and HA and Octoprint) would mean at least 4 of them, totalling at 240 bucks (or 300 with SD). For that money, one could get two (or even three) more-than-capable thin clients.
