Refund policies
The following table describes the refund policies for PolarDB-X instances.
Billing method | Refund policy |
Subscription | When you purchase a PolarDB-X subscription instance, you must make an upfront payment based on the subscription duration. If you no longer require the PolarDB-X subscription instance, you can apply for a refund. |
Pay-as-you-go | You are charged for a PolarDB-X pay-as-you-go instance based on your actual resource usage. If you no longer require the PolarDB-X pay-as-you-go instance, you can release the instance. Before you release the instance, make sure that you have backed up or migrated your data. After a PolarDB-X pay-as-you-go instance is released, you are no longer charged for the instance. |
Take note of the following points:
The pay-as-you-go resources of PolarDB-X can be used together with PolarDB-X storage resources. Different discount plans are provided to offset the fees of pay-as-you-go resources. Refunds are not supported for discount plans.
Refunds may also be involved in the scenarios described in the following table. For more information, see the relevant documentation.
