    In the first part in this series, we talked about the nature of processor virtualization on different systems and how this affects the underlying capacity and performance of compute in cloud infrastructure. It is important to understand the nature of the capacity that you are buying out on a cloud because not all systems and hypervisors virtualize compute in precisely the same manner. This has important ramifications for the applications that run on these clouds.

    You will recall that AWS provides at least two metrics for control: ECU (short for EC2 Compute Unit) and vCPU (meaning virtual Central Processing Unit). …
