What’s the point of this?

Seems maybe to be a cloud apologist post - “AWS is inevitable, sure it sucks and is unreliable but that’s the present and future so don’t you dare get to thinking you could make your own redundant systems cause you can’t,”

Seems to be the messsge.

This is terrible advice.

Multi-region architecture is hard, and AWS sure don’t do much to make it easier. Cross-region data transfers are too profitable for them to do that.
