Within an IaaS implementation, which of the following would NOT be a metric used to quantify service charges for the cloud customer? 

Answer options:

A. Memory
B. Number of users
C. Storage
D. CPU

B

Within IaaS, where the cloud customer is responsible for everything beyond the physical network, the number of users on a system would not be a factor in billing or service charges. The core cloud services for IaaS are based on the memory, storage, and CPU requirements of the cloud customer. Because the cloud customer with IaaS is responsible for its own images and deployments, these components comprise the basis of its cloud provisioning and measured services billing.
