> Yet that's what all their produced literature describes.
No, it's not. I've read it. The Well Architected stuff is actually really good about not being AWS only. These are generally good principals to keep in mind regardless of which provider you go with. And that's how it's written, and that's how AWS teaches it in person (I've actually been through their Well Architected course). Yes, they use AWS tooling to teach it, but nothing about it requires AWS.
So, no. You are completely wrong.
> It's literally a selling point. Not sure how mentioning it is FUD.
Because the pricing AWS has doesn't necessarily increase cost with increase reliability. Suggesting that you need to spend more money to increase reliability is FUD.
> It's FUD (and rightly so) to point out that your cross-platform solution is likely less production-ready and reliable than AWS (in total) as a single point of failure.
That's not what was pointed out. Rather, it was pointed out that you can get high reliability without resorting to multi-cloud and higher costs. For you to continue suggesting otherwise, you first have to start off by explaining why you think high availability can't be obtained using a single cloud provider.
