At one time I had a project to run a cryptocurrency node for BSC (this is basically a fork of Ethereum with all the performance settings cranked up to 11, and blocks centrally issued instead of being mined). It's very sensitive to random access disk throughput and latency. At the time I had a few tiny VPS on AWS and a spinning drive at home, so I evaluated running it there. Even besides the price, you simply cannot run it on AWS EBS because the disk is just too slow to validate each block before the next one arrives. I spent a few hundred dollars and bought an NVMe SSD for my home computer instead.
