Services and metering methods supported by CDT

Cloud Data Transfer (CDT) aggregates and bills Internet data transfers and cross-region data transfers for multiple Alibaba Cloud services in a centralized manner. This topic describes the metering methods, maximum bandwidths, and Service Level Agreements (SLAs) for the Alibaba Cloud services supported by CDT.

CDT bills Internet data transfers and cross-region data transfers in a centralized manner. The following table describes the services for which CDT supports billing.

Note

After you activate CDT and use CDT to bill data transfers for Alibaba Cloud services, all existing and new pay-by-data-transfer instances are automatically billed in CDT in a centralized manner, and pay-by-bandwidth instances continue to be billed in the Alibaba Cloud services. You can query your CDT bills on the Bill Details page in the Expenses and Costs console.
Check whether you have a pay-by-data-transfer instance. If you only activate CDT but do not have a pay-by-data-transfer instance, you do not enjoy the data transfer benefits of 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, you cannot be billed by CDT, you can Migrate ECS instances from the classic network to a VPC to be billed by CDT.

Maximum bandwidths and SLAs for the services supported by CDT

The following table provides the maximum bandwidths and SLAs of pay-by-data-transfer instances for the services supported by CDT. You can use bandwidths based on your business requirements.

Note

If you need a higher bandwidth, contact your account manager.

Supported service	Maximum bandwidth	SLA
ECS	100 Mbps	Service availability of at least 99.995% for a multi-zone instance. Service availability of at least 99.975% for a single-zone instance.
EIP	200 Mbps	Service availability of at least 99.95% for a multi-zone instance. Service availability of at least 99.00% for a single-zone instance.
Anycast EIP	1000 Mbps	None.
Internet Shared Bandwidth	2000 Mbps	Service availability of at least 99.95% for a multi-zone instance. Service availability of at least 99.00% for a single-zone instance.
IPv6 Gateway	1000 Mbps	Service availability of at least 99.95% for a multi-zone instance.
CLB	For each Alibaba Cloud account, the sum of the maximum bandwidths of all pay-by-data-transfer Internet-facing CLB instances in a region cannot exceed 5 Gbit/s.	Service availability of at least 99.95% for a multi-zone instance. Service availability of at least 99.00% for a single-zone instance.
GA	10 Gbps	Service availability of at least 99.95%.
CEN	Region in the Chinese mainland: 1 Gbit/s. Region outside the Chinese mainland/Cross-border: 100 Mbit/s.	Service availability of at least 99.95%.
VPC peering connection	Same region: unlimited. Cross-region/Cross-border: 1,024 Mbit/s.	Same region: none. Cross-region: service availability of at least 99.95%.
ECR	Connections created between regions in the Chinese mainland: 1,000 Mbit/s. Connections created between regions in the Chinese mainland and outside the Chinese mainland: 100 Mbit/s. Connections created between regions outside China: 100 Mbit/s. Note If you want to create multiple connections, the data transfer fees are multiplied by N based on the single-connection data transfer fees. N indicates the number of connections, which is generally four.	Service availability of at least 99.95%.
