I hope you don't wake up 7 hours after a budget alert because you're in the wrong timezone. Please stop justifying the huge risks AWS knowingly carries. It would be easy to place a hard cap, but they refuse to do so.

AWS gives you all the tools you need to shoot your foot off, they also give you all the tools you need to avoid this. I can easily hook up a budget alert to a pushover alert on my phone that is just as likely to wake me up as any alert duty would.

Most people don't have alert duty. I don't want alert duty. I want safety and it's extremely easy to provide it.

You just said that there's a danger of not waking up to a budget alert, and then you say you don't want alert duty. Make up your mind.
