Which method is used to track the cost of consuming public cloud?

Per-user licenses are a traditional software licensing model and do not reflect how public cloud resources are billed, which is based on actual resource consumption rather than named user seats.

Right-to-use tools describe a licensing entitlement concept and do not specifically address the method for tracking or measuring consumption costs in a public cloud billing model.

On-demand licenses with no restrictions describe an access model rather than a mechanism for measuring, reporting, and tracking actual resource usage and associated costs.

Cloud providers offer built-in cost management and monitoring tools such as AWS Cost Explorer, Azure Cost Management, and GCP Billing that give users real-time visibility into resource utilization and spending, enabling accurate cost attribution and optimization without requiring pre-purchased or per-user license agreements.
