The BP runs on a RaspberryPi4 with 4 core, 8G RAM just fine. The Relay could do with a bit more RAM at times. CPU wise, these nodes are mostly bored. The picture may look different when Alonzo smart contracts come live.
I appreciate the response. I may go that route - 4core, 8GB and SSD … I’m still experiementing with higher tier AWS, but it is easy enough to host myself …
