Their pricing page is so confusing: CPU: $0.00000772 per vCPU / sec

This seems to imply $40 / month for 2 vCPU which seems very high?

Or maybe they mean "used" CPU versus idle?

Billing per used or not idle cpu cycle would be quite interesting. Number of cores would just effectively be your cost cap. Efficiency would be even more important. And if the provider over subscribes cores you just pay less. Actually that's probably why they don't do it...
