Cloud Data Transfer (CDT) supports the pay-as-you-go billing method. This topic describes the data transfer types, billing rules, and billing cycles supported by CDT.
After you enable CDT billing for Alibaba Cloud products, CDT automatically bills the data transfers incurred by all existing and new pay-by-data-transfer instances. If new Alibaba Cloud products are supported by CDT, CDT automatically bills the data transfers of the pay-by-data-transfer instances of the products. You can go to the CDT console to view the products that are supported by CDT.
If your ECS instance is in a virtual private cloud (VPC), you can be billed by CDT. If your ECS instance is in a classic network type, you cannot be billed by CDT, you can Migrate ECS instances from the classic network to a VPC to be billed by CDT.
Billing method
CDT supports the pay-as-you-go billing method and has the following features:
You can use CDT to aggregate and bill the Internet data transfers of multiple Alibaba Cloud services in each region that provide access to the Internet based on tiered pricing.
You can use CDT to bill cross-region data transfers based on the pay-by-data-transfer metering method. Tiered pricing is not supported.
CDT only bills Alibaba Cloud products. If you want to upgrade an instance, downgrade an instance, or change the billing method of an Alibaba Cloud product, you must perform the corresponding operations in the console of the corresponding Alibaba Cloud product.
The following table describes products that provide access to the Internet, products that provide cross-region access, and their billing rules.
