A basic bandwidth plan provides bandwidth for data transfer over the Internet and within internal networks of Alibaba Cloud. However, the basic bandwidth plan is not applicable to data transfer between the Chinese mainland and areas outside the Chinese mainland. To accelerate data transfer, you must purchase a basic bandwidth plan.
Bandwidth types
The following types of basic bandwidth plans are supported: basic, enhanced, and premium.
The following table shows that the acceleration type, accelerated backend service,
and acceleration scope of a basic bandwidth plan vary based on the bandwidth type.
| Bandwidth type | Acceleration type | Accelerated backend service | Acceleration scope |
|---|---|---|---|
| Basic | Applications that are deployed on Alibaba Cloud |
|
By default, the acceleration region and the region where the backend service is deployed are located in the Chinese mainland. |
| Enhanced |
|
|
By default, the acceleration region and the region where the backend service is deployed are located in the Chinese mainland. |
| Premium |
|
|
By default, the acceleration region and the region where the backend service is deployed are located in areas outside the Chinese mainland. If you want to accelerate data transfer between the Chinese mainland and other areas, you must select China (Hong Kong) as the acceleration region. |
Note
- By default, you cannot specify ECS instances, internal-facing CLB instances, and internal-facing ALB instances as endpoints for standard GA instances. If you want to specify them as endpoints, submit a ticket.
- You can associate only basic bandwidth plans whose bandwidth types are Basic or Premium with basic GA instances. The endpoint must be a CLB instance that is deployed in a virtual private cloud (VPC) or a secondary ENI.
