Overview

If the current billing mode of resources does not meet service requirements, you can change the billing mode to a more appropriate one.

Pay-per-use: Pay only for the actual resource usage.

Yearly/Monthly: Subscribe to resources for 1 month, 1 year, multiple months, or multiple years. After the subscriptions are successful, resources are allocated to customers. If customers do not renew these resources before they expire, the resources will be released.
