Billing rules for data transfer - Global Accelerator - Alibaba Cloud Documentation Center

After you purchase a Global Accelerator (GA) instance whose bandwidth metering method is pay-by-data-transfer, you are charged for data transfer over the global transmission network of Alibaba Cloud. Data transfer fees are managed by Cloud Data Transfer (CDT). This topic describes the billing rules for data transfer.

Prerequisites

An Internet Content Provider (ICP) number is obtained for the service domain name if your service requires acceleration between regions in the Chinese mainland and regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan). Otherwise, you cannot use Global Accelerator.

Billable items

The data transfer of a Global Accelerator instance whose bandwidth metering method is pay-by-data-transfer includes the following types:

The Internet data transfer between clients and the acceleration region.
Click to view the supported ISP line types, including BGP (Multi-ISP) and BGP Pro.
- BGP (Multi-ISP): provides premium BGP lines across the globe. This is the default line type. BGP lines from different ISPs can be used. The optimal BGP line is automatically selected to ensure network stability.
  All acceleration regions support BGP (Multi-ISP).
- BGP Pro: BGP (Multi-ISP) Pro lines optimize data transmission to the Chinese mainland and improve connection quality for international services. Cross-border connections are established by using Chinese mainland ISP services when BGP (Multi-ISP) Pro lines provide services to users in the Chinese mainland (except data centers). This reduces network latency.
  BGP (Multi-ISP) Pro is available only in the China (Hong Kong) and Japan (Tokyo) regions.
The data transfer between the acceleration region and the endpoint group over the acceleration network of GA.
Data transfer over the acceleration network of GA can be classified into the following types based on where the service is deployed:
- Inter-region data transfer: Data is transmitted between regions in the Chinese mainland or between regions outside the Chinese mainland.
- Cross-border data transfer: Data is transmitted between regions in the Chinese mainland and regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan).
  You must select the transmission network type only if your service requires cross-border acceleration between the Chinese mainland and regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan). Supported types: BGP (Multi-ISP) Pro and Cross-border Express Connect.
  BGP (Multi-ISP) Pro: BGP (Multi-ISP) Pro lines are used for network acceleration between regions in the Chinese mainland and regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan).
  You do not need to perform enterprise real-name verification.
  Cross-border Express Connect: Cross-border Express Connect circuits are used for network acceleration between regions in the Chinese mainland and regions outside the Chinese mainland, including China (Hong Kong), China (Macao), and China (Taiwan).
  Cross-border Express Connect circuits provide better acceleration performance but require enterprise real-name verification.
Note
- The region where the service is deployed is determined by the configurations of the acceleration area and the endpoint group.
- If the acceleration region is the same as the region where the endpoint group is deployed, you are not charged for data transfer over the acceleration network of GA.
The Internet or internal data transfer between the endpoint group and the backend service.
Data is transmitted over the Internet or internal networks based on the method used to connect to the backend service. You are not charged for internal data transfer.

The following table describes the billable items for data transfer in different scenarios.

Example 1: Clients in the Chinese mainland access an application deployed outside Alibaba Cloud in the Chinese mainland

In the following figure, the acceleration region is the China (Shanghai) region, the endpoint group is deployed in the China (Beijing) region, and the endpoint is deployed outside Alibaba Cloud. Requests are routed to the endpoint over the Internet. After a Global Accelerator instance is purchased, 1,000 GB of data is transferred within a month. The data transfer fees include the Internet data transfer fee in the China (Shanghai) region, the Internet data transfer fee in the China (Beijing) region, and the inter-region data transfer fee.

Unit price of Internet data transfer in the Chinese mainland = USD 0.118 per GB
Unit price of inter-region data transfer between regions in the Chinese mainland = USD 0.09 per GB
The data transfer fees are calculated by using the following formulas:
Internet data transfer fee in the China (Shanghai) region = Unit price of Internet data transfer in the Chinese mainland × Amount of data transfer = USD 0.118 per GB × 1,000 GB = USD 118
Internet data transfer fee in the China (Beijing) region = Unit price of Internet data transfer in the Chinese mainland × Amount of data transfer = USD 0.118 per GB × 1,000 GB = USD 118
Inter-region data transfer fee = Unit price of inter-region data transfer between regions in the Chinese mainland × Amount of data transfer = USD 0.09 per GB × 1,000 GB = USD 90
Total data transfer fee = Internet data transfer fee in the China (Shanghai) region + Internet data transfer fee in the China (Beijing) region + Inter-region data transfer fee = USD 118 + USD 118 + USD 90 = USD 326

Example 2: Clients outside the Chinese mainland access an application deployed on Alibaba Cloud outside the Chinese mainland

In the following figure, the acceleration region is the Singapore region, the endpoint group is deployed in the US (Silicon Valley) region, and the endpoint is deployed on Alibaba Cloud. Requests are routed to the endpoint over the internal network. After a Global Accelerator instance is purchased, 1,000 GB of data is transferred within a month. The data transfer fees include the Internet data transfer fee in the Singapore region and the inter-region data transfer fee.

Unit price of Internet data transfer in Asia Pacific = USD 0.100 per GB
Unit price of inter-region data transfer from Asia Pacific to North America = USD 0.08 per GB
The data transfer fees are calculated by using the following formulas:
Internet data transfer fee in the Singapore region = Unit price of Internet data transfer in Asia Pacific × Amount of data transfer = USD 0.100 per GB × 1,000 GB = USD 100
Internet data transfer fee in the US (Silicon Valley) region = USD 0
Inter-region data transfer fee = Unit price of inter-region data transfer from Asia Pacific to North America × Amount of data transfer = USD 0.08 per GB × 1,000 GB = USD 80
Total data transfer fee = Internet data transfer fee in the Singapore region + Internet data transfer fee in the US (Silicon Valley) region + Inter-region data transfer fee = USD 100 + USD 0 + USD 80 = USD 180

Example 3: Clients in the Chinese mainland access an application deployed on Alibaba Cloud outside the Chinese mainland

In the following figure, the acceleration region is the China (Shanghai) region, the endpoint group is deployed in the US (Silicon Valley) region, and the endpoint is deployed on Alibaba Cloud. Requests are routed to the endpoint over the internal network. After a Global Accelerator instance is purchased, 1,000 GB of data is transferred within a month. The data transfer fees include the Internet data transfer fee in the China (Shanghai) region and the cross-border data transfer fee for BGP (Multi-ISP) Pro lines.

Unit price of Internet data transfer in the Chinese mainland = USD 0.118 per GB
Unit price of cross-border data transfer from the Chinese mainland to regions outside the Chinese mainland over BGP (Multi-ISP) Pro lines = USD 0.96 per GB
The data transfer fees are calculated by using the following formulas:
Internet data transfer fee in the China (Shanghai) region = Unit price of Internet data transfer in the Chinese mainland × Amount of data transfer = USD 0.118 per GB × 1,000 GB = USD 118
Internet data transfer fee in the US (Silicon Valley) region = USD 0
Cross-border data transfer fee over BGP (Multi-ISP) Pro lines = Unit price of cross-border data transfer from the Chinese mainland to regions outside the Chinese mainland over BGP (Multi-ISP) Pro lines × Amount of data transfer = USD 0.96 per GB × 1,000 GB = USD 9,600
Total data transfer fee = Internet data transfer fee in the China (Shanghai) region + Internet data transfer fee in the US (Silicon Valley) region + Cross-border data transfer fee over BGP (Multi-ISP) Pro lines = USD 118 + USD 0 + USD 9,600 = USD 9,718
