Upgrade to CDT billing to consolidate Internet traffic usage and billing across your cloud services.
Usage notes
-
After you upgrade to CDT billing, CDT centrally bills and invoices all existing and new pay-by-traffic instances. Their original cloud services continue to bill for instances that use the pay-by-bandwidth billing method.
You can go to the Expenses and Costs console and view your CDT bills on the page.

After you upgrade to CDT billing, you receive a free quota of 220 GB/month of Internet traffic. This quota provides 20 GB/month for the Chinese mainland and 200 GB/month for regions outside the Chinese mainland.
Procedure

Log on to the CDT console and view the details in the Upgrade to CDT Billing for Cloud Services section.

Effective June 1, 2025, CDT provides a free monthly quota of 220 GB of Internet traffic (20 GB for the Chinese mainland, 200 GB for regions outside the Chinese mainland). This quota offsets Internet traffic costs for ECS, EIP, and Classic Load Balancer (CLB). Besides Not upgraded and Upgraded by default, the status can be Upgraded, indicating a completed manual upgrade. For services not yet upgraded (such as ECS and shared bandwidth), click Upgrade in the Actions column. For all services, click Create Instance to create a pay-by-traffic instance.
