I have Pi's and old, beefy computers and what I really need is an "elastic personal cloud" where I can bring up the high-powered computer(s) online on demand[1]. I have WiFi-connected sockets and a python script than can turn them on or off, but no orchestration or global state. 1. My 12-year old, former top-of-the-line laptop is much faster than my 3rd-gen Pi when periodically ingesting and indexing JSON into a PostgeSQL db, I suspect slow IO and limited memory are to blame.

I have used wake on LAN sometimes for this too, but that was close enough for me, and I lost interest. WoW (wake on wife), worked pretty well from the office, but I seem to get a little bit of latency and packet loss. Now I work from home, so I just get up and hit the power button on the more powerful machines. My shock with compute power was when I got the Pi 4. It was faster than the AMD e350 I was using for backups except for disk IO. The E350 was not a powerful machine new, but I didn't realize how far we had come. A USB 3 enclosure brought it to a level that was good enough the entire mini ITX build was pointless to keep around.
