Amazon surely allocates their resources in advance of prime day, so they can preemptively change prices to account for demand or deny requests.

That said, why would capacity issues be behind NDA? Anyone can grab their API and attempt to allocate a VM (or 100k)

You can query the spot pricing api and see what’s going on with that. I have a feeling Amazon purposely tries not to hang their customers out to dry by consuming large amounts of spot instances, or on-demand tanking spot availability.

Just a chilling effects from general paranoia over breaking NDA. What is and isn't actually covered by the NDA isn't something I had the time to look up for my comment for.

You can't spin up 100k instances on a virgin account, but it's an interesting idea!
