> But with AWS, you're sold the story of infinite compute you can just expect to be there, but you'll quickly find out just how stingy they can get with giving you more hardware automatically to scale to.
This is key.
Most people never scale to a size where they hit that limit, and in most organisations where that happens, someone else have to deal with it, and so most developers are totally unaware of just how fictional the "infinite scalability" actually is.
Yet it gets touted as a critical advantage.
At the same time, most developers have never ever tried to manage modern server harware, and seem think it is somehwat like managing the hardware they're using at home.
But that limit is well below on what you could get even in a gaming machine (AWS cpus are SMT threads, so a 32 core machine is actually 64 cpus by AWS) - you can get that in a high end workstation, and I'd guess that's way more power than most people end up using even in their large-ish scale AWS projects.

Not on the AMD machines from m7 (and the others which share the same architecture)
