AWS is basically a utility. I think it's inevitable that their carelessness around billing will end up with them being regulated like one.

That’s why you always use a spend limited card with variable cost providers.

I wouldn't expect their detection of hacked accounts to be 100% correct. Sure, it might be obvious when a human takes a look, but humans can't proactively look at every account's usage.

Service provider lesson #1: Never ever ever enable auto-pay! The convenience (and even the savings, if applicable) aren't worth the risk of the service provider autonomously slurping up all your money.

For a while I had a portion of my "homelab" on AWS. I was an educator in a classroom where the students were learning cloud stuff, and the instructor was encouraging the students to stand-up cloud environments for learning, so I figured that I would do the same.

I used AWS' free tier, of course, and I enjoyed the initial setup in EC2, and I did a LAMP-stack MediaWiki installation. It wasn't too difficult, but two things sent me away forever.

1. It was impossible, or at least highly labor-intensive, in this modern era to adequately secure an ordinary Linux system running Internet-facing services. I put fail2ban and I filtered a lot of ports, and still spammers attacked me on Layer 7.

2. It was impossible, actually impossible, to limit or cap my cloud expenses in any billing cycle. Sure, run free-tier all I want. Sure, come in within the limits almost every month. But if I configured one thing wrong, or one thing went runaway, I'd have a sizable bill that I couldn't dispute. And even worse, those "runaways" weren't necessarily things in my sphere of control, but could be triggered by basically anyone coming in and using my VPC resources, especially egress network traffic.

So I closed out my cloud account, and I developed a lot of sympathy for businesses and corps that now are forced to run "in the cloud" rather than on-prem or their own machine rooms, but now they have no way to control expenses.

Right, and good luck getting a correct bill from Azure. And when you are finally fed up, it will take months to close your Azure account.
