Cloud providers assume everyone is just like them, or like Netflix: Load balancers in clusters balancing groups of clusters. Clusters of clusters. Many regions. Many availability zones. Anything can be lost, because an individual data centre is just 5% of the total, right?

Meanwhile most of my large government customers have a couple of tiny VMs for every website. That's it. That's already massive overkill because they see 10% max load, so they're wasting money on the rest of the resources that are there only for redundancy. Taking things to the next level would be almost absurd, but turning things off unnecessarily is still an outage.

This is why I don't believe any of the Cloud providers are ready for enterprise customers. None of you get it.
