If you’re looking to try learning about cluster management without running up a huge AWS bill, sure. But you’re not going to be doing anything with it you couldn’t do with some random PC with way more cores and horsepower, plus way more RAM (the vast majority of that 2GB in each box is going to be going to running the OS and the cluster client).

If you could get a bunch of PS3s or ASICs free, then you could actually do work that could net you some money: mine crypto (if it’s even worth doing at any given time based on electricity cost).

Plus the entire thing would likely be pulling way more power too, and take up 10-20x the space.
