What will they put on the feet of their walkers?

Haha. That was my wedding night. Funny and sad in equal measure.

Pretty much this. There is a significant learning curve to kubernetes (or similar, I guess?), but it’s a handy skill to be familiar with. If things basically run but with degraded performance on one raspberry, there is no real need for a vertical performance increase. Adding the second will provide almost double capacity, with some HA added for fun.

If containerized, scale horizontal and load balance.

I guess my cutoff would be actual conversation. Unless they specifically ask to be eaten, ala the bit from Hitchiker’s Guide, in which case I guess the sky is the limit.
