I remember trying AWS Glacier as a broke university student, thinking it was a cheap way to back up my data. I was wrong.

A decade later I played around with AWS, set up a free 1-core VPS. It was fine for a year or so (I ended up not using it at all), and suddenly I got a bill. It wasn't much, but it reminded me how these services make it very hard to be aware of your bills until you get them.

I was trying out Azure recently, and I found it too confusing to make any sort of quick risk assessment.

It's clearly just for people for whom "What's the worst that could happen?" is always a rethorical question.
