Edge Security Acceleration:Billing of basic services

Last Updated:Oct 12, 2024

The basic services of Alibaba Cloud Dynamic Content Delivery Network (DCDN) support two metering methods: pay-by-data-transfer and pay-by-peak-bandwidth. You can select a metering method as needed. This topic describes the metering methods and considerations for the basic services of DCDN.

Pay-by-data-transfer (default)

Scenario

Billing rule

Websites that experience greatly fluctuating traffic and spikes in bandwidth usage, with daily bandwidth usage below 30%

  • Description: You are billed for the monthly outbound data transfer of DCDN points of presence (POPs) based on tiered pricing.

  • Billable item: traffic.

  • Billing method: pay-as-you-go or subscription.

  • Billing cycle: You are billed on an hourly basis. A bill is generated about 3 to 4 hours after the end of a billing cycle. The time when bills are generated is determined by the system.

    Note

    Pay-as-you-go: You are charged based on the outbound data transfer.

Pay-by-peak-bandwidth

Important

To use the pay-by-peak-bandwidth metering method, make sure that the peak bandwidth value within the previous 30 days exceeds 5 Gbit/s and contact your account manager or contact us by other means.

Scenario

Billing rule

Websites whose network traffic is relatively flat and daily bandwidth usage exceeds 30%

  • Description: You are charged based on the daily peak bandwidth. Bandwidth data is collected every 5 minutes, resulting in a total of 288 records per day. The highest bandwidth is used as the billable daily peak bandwidth.

  • Billable item: peak bandwidth.

  • Billing method: pay-as-you-go.

  • Billing cycle: You are charged on a daily basis. The bills of a day are generated and the amount due is deducted after 00:00 on the following day. The time when bills are generated is determined by the system.

Burst bandwidth

Due to business expansion, data transmission abuse, or attacks, your domain may experience burst bandwidth usage.

  • In the pay-by-peak-bandwidth metering method, the following cases can be considered as burst bandwidth usage for a single Alibaba Cloud account:

    • The total increase in bandwidth usage exceeds 500 Gbit/s within a calendar month.

    • The peak bandwidth recorded in the last calendar month was 0, while the total bandwidth increase in the current calendar month exceeds 200 Gbit/s.

    • The total peak bandwidth usage in the current calendar month is 1.3 times the billable bandwidth of the previous calendar month.

  • In the pay-by-data-transfer metering method, if the peak bandwidth of a single domain exceeds 100 Gbit/s within a calendar month, it can be considered as burst bandwidth usage.

  • If otherwise agreed, the actual rule prevails.

If you expect burst bandwidth on DCDN-accelerated services, you need to apply for burst bandwidth at least 3 business days in advance. For major events including but not limited to the Spring Festival Gala and Double 11 Global Shopping Festival, you need to apply for burst bandwidth at least 1 month in advance. If the application is approved, the availability of your services is guaranteed when the burst bandwidth is within the level agreed upon by both parties. If you do not apply for burst bandwidth or the application is not approved, Alibaba Cloud reserves the right to take measures such as bandwidth throttling to ensure service-level stability for other Alibaba Cloud customers. Alibaba Cloud is not responsible for the reduced availability caused by the measures.

To apply for burst bandwidth, contact your account manager or contact us by other means. After the application is approved, you are billed based on the newly agreed price. If you do not apply for burst bandwidth or the application is rejected, you are billed based on the current price. The final fees are determined by DCDN bills.
