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.
CDT is an out-of-the-box service that separates resource use and management from resource billing. You are not charged for activating CDT. Alibaba Cloud services provide resource management features, and CDT manages the bills of data transfers of Alibaba Cloud services in a centralized manner.
After you activate CDT and enable CDT billing for Alibaba Cloud services, CDT automatically bills the data transfers incurred by all existing and new pay-by-data-transfer instances. If new Alibaba Cloud services are supported by CDT, CDT automatically bills the data transfers of the pay-by-data-transfer instances of the services. You can go to the CDT console to view the services that are supported 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 the inter-region data transfers of services that provide inter-region access based on the pay-by-data-transfer billing method. Tiered pricing is not supported.
CDT only bills Alibaba Cloud services. If you want to upgrade an instance, downgrade an instance, or change the billing method of a service, you must perform the corresponding operations in the console of the corresponding Alibaba Cloud service.
The following table describes services that provide access to the Internet, services that provide inter-region access, and their billing rules.
