You can change the billing method of a PolarDB cluster from subscription to pay-as-you-go based on your business requirements.

Prerequisites

  • Your cluster is in the Running state.
  • Your cluster is not in the progress of a temporary upgrade.
  • Make sure that your account balance is sufficient to prevent service downtime that is caused by overdue payments after you switch the billing method to pay-as-you-go.

Pricing

After you change the billing method of the cluster from subscription to pay-as-you-go, a subscription refund is returned to your original payment account.

Refund = (Number of remaining days/Total days) × Order cash amount

Note
  • The order cash amount indicates the actual paid cash amount that excludes vouchers and coupons.
  • You are not charged for service fees when you change the billing method from subscription to pay-as-you-go.
