There are shared resources in different regions. Electricity. Cables. Common systems for coordination.

Your experiment proves nothing. Anyone can pull it off.

The sites were chosen specifically to be more than 50 miles apart, it proved plenty.

I am the CEO of your company. I forgot to pay the electricity bill. How is the multi-region resilience going?

If you go far up enough the pyramid, there is always a single point of failure. Also, it's unlikely that 1) all regions have the same power company, 2) all of them are on the same payment schedule, 3) all of them would actually shut off a major customer at the same time without warning, so, in your specific example, things are probably fine.

I suspect 'whatever1' can't be satisfied, there are no silver bullets. There's always a bigger fish/thing to fail.

The goal posts were fine: bomb the AZ of your choice, I don't care. The Cloud [that isn't AWS, in the case of 'us-east-1'] will still work.

No. It’s just that in my entire career when anyone claims that they have the perfect solution to a tough problem, it means either that they are selling something, or that they haven’t done their homework. Sometimes it’s both.

For what's left of your career: sometimes it's neither. You're confused, perfection? Where? A past employer, who I've deliberately not named, is selling something: I've moved on. Their cloud was designed with multiple-zone regions, and importantly, realizes the benefit: respects the boundaries. Amazon, and you, apparently have not.

Yes, everything has a weakness. Not every weakness is comparable to 'us-east-1'. Ours was billing/IAM. Guess what? They lived in several places with effective and routinely exercised redundancy. No single zone held this much influence. Service? Yes, that's why they span zones.

Said in the absolute kindest way: please fuck off. I have nothing to prove or, worse, sell. The businesses have done enough.

This is not what the resilience expert stated.

If your accounts payable can’t pay the electric bill on time, you’ve got bigger problems.

Yea, let's play along. Our CEO is personally choosing to not pay any entire class of partners across the planet. Are we even still in business? I'm so much more worried about being paid than this line of questioning.

A Cloud with multiple regions, or zones for that matter, that depend on one is a poorly designed Cloud; mine didn't, AWS does. So, let's revisit what brought 'whatever1', here:

> Your experiment proves nothing. Anyone can pull it off.

Amazon didn't, we did. Hmm.

Fine, our overseas offices are different companies and bills are paid for by different people.

Not that "forgot to pay" is going to result in a cut off - that doesn't happen with the multi-megawatt supplies from multiple suppliers that go into a dedicated data centre. It's far more likely that the receivers will have taken over and will pay the bill by that point.

Fine, the tab increments. Get back to hyping or something, this is not your job.

I doubt it should be yours if this is how you think about resilience.

Your vote has been tallied

Same failure mode of anything else.

How’s not paying your AWS bill going for you?

if the ceo of your company is personally paying the electric bill, go work for another company :)
