IaaS Metrics for Cloud Customers

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.

Within an Infrastructure as a Service (IaaS) implementation, cloud service providers typically charge customers based on the amount of resources they consume. This is commonly referred to as "pay-as-you-go" pricing, where customers only pay for the computing resources they use.

The most common resources that are used to quantify service charges for IaaS customers are:

A. Memory: This refers to the amount of RAM allocated to a customer's virtual machine (VM). Customers are typically charged based on the amount of memory they consume on a per-hour or per-month basis.

B. Number of users: This refers to the number of user accounts or login credentials that are provisioned for a customer's application or service. Customers are typically charged based on the number of users that access their application or service.

C. Storage: This refers to the amount of storage space allocated to a customer's VM. Customers are typically charged based on the amount of storage they consume on a per-hour or per-month basis.

D. CPU: This refers to the amount of processing power allocated to a customer's VM. Customers are typically charged based on the amount of CPU they consume on a per-hour or per-month basis.

Therefore, all of the options A, B, C, and D are commonly used metrics to quantify service charges for IaaS customers. Therefore, the correct answer to the question is "None of the above" as all of them can be used to quantify service charges.
