Part of the supposedly unbreakable Amazon cloud was down, and the world didn’t end.
What did happen was that a swarm of the best operations people in the world rapidly descended on the problem, diagnosed and fixed it. You can be sure the issue had top management attention, because Amazon’s brand, reputation, and business rides on their infrastructure.
With all due respect to your infrastructure and operations team, they are unlikely to have the manpower, specialization, and training that Amazon cloud engineering has. If the same issue had hit your own in-house data center, it would have taken you much longer to find and fix it.
That’s why you want to be in the cloud. As long as you can move to another cloud.
