That's interesting, it didn't used to be linear, particularly on the very large instances. Oddly when looking at the prices for RHEL those are much closer to what all the prices used to look like (I hadn't actually looked at AWS pricing in a few years). I wonder if AWSes virtualization tech has just reached the point now where all processing is effectively fungible and it's all really just executing on clusters of mid-range CPUs no matter how large your virtual server is.
