Tair:Change the billing method to pay-as-you-go

Last Updated:Mar 04, 2024

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

Prerequisites

The instance is billed on a subscription basis and is in the Running state.

Note

If the instance changes to a state such as Locked before you pay for an order for changing the billing method, your payment may fail. After the state of the instance changes back to Running, you can resume paying for the order.

Billing

After you change the billing method of a Tair instance to pay-as-you-go, a refund is returned by using the method used to pay for the instance. Coupons and vouchers cannot be refunded.

The refund is calculated by using the following formula: Refund = Fee actually paid - Fee for consumed resources.

  • The fee actually paid is the money that you paid and does not include the amount covered by coupons or vouchers.

  • The fee for consumed resources is calculated based on the following formula: Fee for consumed resources = Daily fee × Consumed subscription duration × Discount for the consumed subscription duration. The daily fee is equal to the order-specific fee divided by 30.

    Note

    The consumed subscription duration is accurate to the day. The part that is less than one day is counted as one day.

Usage notes

  • When you change the billing method of a Tair instance to pay-as-you-go, the workloads on the instance are not interrupted.

    Important

    Each pay-as-you-go Tair instance is billed and paid by hour. To prevent overdue payments that may cause downtime, make sure that your account balance is sufficient.

  • The subscription billing method is more cost-effective than the pay-as-you-go billing method, and you are offered higher discounts for longer subscription periods. For long-term use, we recommend that you select the subscription billing method.

  • Billing method switch is not available for instances that use phased out instance types.

Procedure

  1. Log on to the Tair console and go to the Instances page. In the top navigation bar, select the region in which the instance that you want to manage resides.

  2. Find the instance for which you want to change the billing method and choose 更多 > Switch to Pay-as-you-go Billing in the Actions column.

  3. On the page that appears, read the notes and check the refund amount in the lower part of the page.

    Note

    For more information about the refund, see the "Billing" section of this topic.

  4. Read and select the Terms of Service that is displayed.

  5. Click Buy Now.
