This topic describes the rules for using resource plans to offset resources fees.

Rules for applying individual resource plans

  • A resource plan takes effect immediately after you complete the payment for the resource plan.
  • Each type of resource plan can be used only to offset a specified type of fee.

    Outbound data transfer plans can be used to offset only outbound data transfer fees. They cannot be used to offset fees of other billable items such as HTTPS requests.

  • Outbound data transfer plans can be used to offset outbound data transfer fees only if the metering method of Alibaba Cloud CDN is pay-by-data-transfer. Each data transfer plan is effective only in the accelerated region that is specified when you make the purchase.

    For example, an outbound data transfer plan for the mainland China accelerated region can be used to offset outbound data transfer fees only in mainland China. You cannot use it to offset outbound data transfer fees in China (Hong Kong), China (Macao), China (Taiwan), or other regions outside mainland China.

  • If a resource plan expires or is exhausted, consumed resources are automatically billed on a pay-as-you-go basis.
  • After a resource plan takes effect, it may take 3 to 4 hours to offset the resource fees.

    For example, Alice purchased an outbound data transfer plan of 1 TB for the mainland China accelerated region at 10:30:30 (UTC+8) on August 12, 2021. The data transfer plan was valid for one month. In this case, the time when outbound data transfer fees were offset was around 14:00:00 (UTC+8) on August 12, 2021. Outbound data transfer fees were not offset until the system generated the data transfer bill of the billing cycle from 10:00:00 to 11:00:00.

Order for applying resource plans of the same type

If you purchase multiple resource plans of the same type, they are applied in order of expiration times. The resource plan with the earliest expiration time is applied first. The number of resources that exceeds the resource plans is billed on a pay-as-you-go basis.

For example, Alice purchased an outbound data transfer plan of 1 TB for the mainland China accelerated region on July 1, 2021. The outbound data transfer plan was valid for one year. On August 1, 2021, Alice purchased another outbound data transfer plan of 1 TB for the mainland China accelerated region. The outbound data transfer plan was valid for 6 months. In this case, the outbound data transfer plan that was purchased on August 1, 2021 was applied first.
