This topic describes how to change the billing method of an RDS for MariaDB instance from pay-as-you-go to (monthly or annual) subscription.

Impacts

Changing the billing method does not interrupt the running of your RDS instance.

Precautions

  • You cannot change the billing method of an RDS instance from subscription to pay-as-you-go. To optimize your cost plan, you must evaluate your usage model thoroughly before you change the billing method of your RDS instance.
  • If an RDS instance has an unpaid subscription order, the subscription order becomes invalid after you upgrade the instance type. In such case, you must first go to the Orders page in the RDS console to cancel the subscription order, and then change the billing method to subscription again.

Prerequisites

  • The instance type cannot be a historical one, which means that the instance type must be available for sale. For more information about historical instance types, see Instance types. Before you change the billing method of a historical-type RDS instance to subscription, you must change the instance type to one that is available for sale. For detailed steps, see Change the configuration of an RDS for MariaDB instance.
  • The RDS instance uses the pay-as-you-go billing method.
