Saying that you can't get IOPS on AWS is like saying that your machinegun sucks at grating cheese. It's really not meant to do that.

But that's fine as AWS isn't the only cloud platform out there, and some are actually desgined to take data intensive workloads.

The problem is that it's touted as a great way to scale web apps. Since DB performance is usually the limiting factor in webapp scaling, this doesn't appear to stack up. Needing a lot of IOPS is pretty par for the course.

For certain workloads it deals ok, but yeah, I'd fully agree with you.

On the other hand, there are plenty of clouds out there that have reasonable IOP performance, so it's not as though it's a monopoly.

I guess my question is why go for reasonable when you can get incredible performance per dollar with RAID-10 SSDs? A few dedicated DB machines with SSDs and many cores can get you absolutely monstrous throughput without going for any of the more exotic DB solutions.

Exactly. And it's not like it's a good idea to put your DB in an IOPs enhanced cloud, and your applications in another.
