Which feature of a private cloud allows tracking of individual resource usage?

The feature of a private cloud that allows for tracking individual resource usage is chargeback. Chargeback involves measuring and reporting on resource consumption by different departments or users within the organization. This enables the IT department to allocate costs based on actual usage, providing transparency and accountability. By implementing chargeback, organizations can ensure that resources are being utilized effectively and can adjust budgets and operations accordingly.

Resource pooling refers to the ability to combine and allocate computing resources dynamically among multiple users or applications, but it does not inherently provide insights into individual resource usage. Rapid elasticity allows for the quick scaling of resources up or down based on demand but does not focus on tracking usage specifics. On-demand self-service allows users to provision resources as needed but similarly does not include functionality for tracking usage metrics. Therefore, in the context of tracking individual resource usage, chargeback is the correct feature that addresses this need effectively.
