This is a really interesting read, but this dude missed a major component of best practices, which is that your architecture needs to be able to respond to a proper disaster, which includes Amazon just dropping out of the sky and nuking your entire account.

Frankly, it's shocking that he didn't have local copies or a home server that he kept backups too. I've seen some people mention that a multi-cloud architecture is hard to set up, which is true, it's also expensive, but I don't think it would be super hard to set up, like, a blob storage in Azure, or a Google Cloud Storage, to just keep backups of whatever you're working on. We should always keep in mind that our accounts getting locked is always a possibility.

It's kinda weird, normally when you hear about things like this, it's the other way around where somebody was running a major production component on personal infrastructure and couldn't handle the bare metal.
