Yearly/Monthly to Pay-per-Use

After creating a yearly/monthly DDM instance, you can change it to pay-per-use for more flexibility, and you can recoup part of what you paid for the subscription.

Assume that you purchased a yearly/monthly DDM instance at 15:29:16 on April 18, 2023 and changed it to pay-per-use billing at 16:30:00 on May 18, 2023. On the Billing Center > Billing page, bills information is generated as follows:

Yearly/Monthly billing: 15:29:16 on April 18, 2023 to 23:59:59 on May 18, 2023
Pay-per-use billing: 00:00:00 on May 19, 2023 - End time of pay-per-use billing. A bill was generated every hour.

The pay-per-use billing mode will be applied only after the yearly/monthly billed duration ends and auto-renew will be not in effect.

Constraints

Resources such as EIPs that are used by a DDM instance may not support the change with this instance. For details about their billing mode change rules and handling methods, see Table 1.
