What about burstable instances on AWS, and whatever is the equivalent in other clouds? Hard to imagine those having a dedicated core, would probably defeat the purpose.
My guess is there's likely less value in trying to target those kinds of environments... Just poking random data out of lambda or low end vps neighbors is a needle in a haystack the size of the moon in terms of finding anything useful.
It's more likely useful as part of a group of exploits to hit an individual, targeted system.
