Thanks, that makes sense. However, sometimes it looks like some of the best engineer's I've worked with can get work done even before technology gets popular enough to have courses :) Also, it can sometimes be hard to create sandboxes. It's easy for Prometheus, but maybe a bit harder to AWS (I tried LocalStack before). Nevertheless it's all good advice, thanks!
