There's all sorts of examples of AWS failing to be able to provide capacity too. Just do a search for "aws InsufficientInstanceCapacity" or similar. I remember Fortnite talking about capacity limits in relation to an incident, but I'm struggling to find the post-mortem I saw it in.

Even when Microsoft was being open about Azure having difficulty getting Intel chips, AWS, GCP etc. were in the same position and just not really talking about it. From my time in AWS there were some other times when some services with specialised hardware came really, really close to running out of capacity and had to scramble around with major internal "fire drills" against services to recoup capacity.

Most people won't run in to these issues, the clouds all tend to be good at it, but they still happen.

There are also advantages of the economy of scale and brand recognition. The more customers you have the more the capacity trends smooth out, the easier it is to predict need, even if you're still stuck with uncertainty on the ordering side.

It’s certainly true I run into these things with AWS as well, but it’s generally limited to a specific instance type/availability zone combination. I’ve never had all instance types unavailable.

If anything, I’m surprised we can just spin up a few hundred instances out of nowhere and not run into capacity issues.

AWS has capacity issues you can generally mitigate. Azure however will just lock you out of a solution completely and tell you to switch regions as if that was some trivial thing.
