Cloud Data Transfer:Cross-region data transfers

Billing

The following content describes the billing rules for different Alibaba Cloud services that provide cross-region access:

• Global Accelerator (GA) and Anycast Elastic IP Address (EIP): Pay-by-dominant-data-transfer is used. You are charged for data transfers in the dominant direction in each region. The direction in which a greater amount of data is transferred is the dominant direction.

• Cloud Enterprise Network (CEN), Virtual Private Cloud (VPC) peering connection, and Express Connect Router (ECR): Pay-by-outbound-data-transfer is used. You are charged for data transfers in each region.

• The cross-region data transfers of CEN support two service levels: Platinum and Gold. You can select a service level based on your business requirements. If you use other products that provide cross-region access, only the Gold service level is supported.

  Service	Service level	Service availability	Scenario
  CEN	Platinum	99.995%	Ideal for services that require high network quality and are sensitive to network jitters and latency, such as securities transactions, online voice chat, video conferencing, and real-time gaming.
  CEN VPC peering connection Anycast EIP GA ECR	Gold	99.95%	Ideal for services that do not have high requirements for network quality, such as data synchronization and file transfer.

Cross-region data transfers are classified into the following categories:

• Local data transfers: Data is transmitted between regions in the Chinese mainland or between regions outside the Chinese mainland.

• Cross-border data transfers: Data is transmitted between regions in the Chinese mainland and regions outside the Chinese mainland.

  Note

Example

Company A creates VPC 1 in the China (Hangzhou) region and VPC 2 in the China (Shenzhen) region, and uses an Enterprise Edition transit router to create a cross-region connection. The line type is set to Gold and the bandwidth allocation mode is set to pay-by-data-transfer. The amount of outbound data transfers in the China (Hangzhou) region is 200 GB, and the amount of outbound data transfers in the China (Shenzhen) region is 100 GB. The fee is calculated by using the following formula:

0.072 USD/GB × 200 GB + 0.072 USD/GB × 100 GB = 21.6 USD
