Cloud Data Transfer (CDT) is an Alibaba Cloud service that manages the billing of bandwidth resources. CDT supports flexible billing and metering methods, such as free quotas, pay-by-data-transfer, and tiered pricing models, to help you reduce bandwidth costs.
CDT supports tiered pricing for Internet data transfers per month in each region. The unit price decreases as the amount of Internet data transfers increases.
CDT supports the pay-by-data-transfer metering method for inter-region data transfers. This metering method is more flexible, and allows you to enable inter-region communication based on business requirements.
Benefits
Free data transfers: Beginning April 8, 2024, the monthly quota on free Internet data transfers provided by CDT is increased from 20 GB to 200 GB. Among the 200 GB of free Internet data transfers, 20 GB can be used in global regions, including regions in the Chinese mainland, and the other 180 GB can be used only in regions outside the Chinese mainland.
Cost effective: CDT supports tired pricing for Interment data transfers. The unit price decreases as the amount of Internet data transfer increases. The tiered pricing model determines the pricing tier based on the total amount of data transfers accumulated from multiple services and bills data transfers for each region.
Flexible metering method: CDT supports the pay-by-data-transfer metering method for inter-region data transfers. This prevents resource waste because you only need to pay for the resources that you use.
Multiple supported services: For more information, see Supported services.
Support for Financial Operations (FinOps): CDT allows you to use FinOps to separate resource creation from resource billing. This improves delivery efficiency. CDT can bill Internet data transfers and inter-region data transfers for different Alibaba Cloud services. CDT also allows you to add tags to resources and split the bills of data transfers that are generated by the resources based on the tags. This improves the collaboration efficiency of the business, ITT, and finance departments, and helps you gain more financial control and predictability.
