A basic bandwidth plan provides bandwidth for data transfer over the Internet and within internal networks of Alibaba Cloud. However, basic bandwidth plans are not applicable to data transfer between the Chinese mainland and areas outside the Chinese mainland. A basic bandwidth plan is required if you want to accelerate data transfer within the Chinese mainland, or between the Chinese mainland and other areas.

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
  • Public IP addresses provided by Alibaba Cloud
  • Elastic Compute Service (ECS)
  • Classic Load Balancer (CLB) (formerly known as SLB)
  • Application Load Balancer (ALB)
  • Object Storage Service (OSS)
By default, the acceleration region and the region where the backend service is deployed are located in the Chinese mainland. You can purchase a cross-border acceleration bandwidth plan to accelerate data transfer between the Chinese mainland and other areas.
Enhanced
  • Applications that are deployed on Alibaba Cloud
  • Applications that are not deployed on Alibaba Cloud
  • Public IP addresses provided by Alibaba Cloud
  • ECS
  • CLB (formerly known as SLB)
  • ALB
  • OSS
  • Custom IP addresses
  • Custom domain names
By default, the acceleration region and the region where the backend service is deployed are located in the Chinese mainland. You can purchase a cross-border acceleration bandwidth plan to accelerate data transfer between the Chinese mainland and other areas.
Premium
  • Applications that are deployed on Alibaba Cloud
  • Applications that are not deployed on Alibaba Cloud
  • Public IP addresses provided by Alibaba Cloud
  • ECS
  • CLB (formerly known as SLB)
  • ALB
  • OSS
  • Custom IP addresses
  • Custom domain names
By default, the acceleration region and the region where the backend service is deployed are located in the 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. You can purchase a cross-border acceleration bandwidth plan to accelerate data transfer between the Chinese mainland and other areas.
Note
  • You can specify ECS, CLB, and ALB instances as endpoints only if your Alibaba Cloud account is included in the whitelist. If you want to specify ECS, CLB, or ALB instances as endpoints for your GA instances, submit a ticket to upgrade the GA instances.
  • If you want to specify ECS instances or CLB instances as endpoints, make sure that the instances are deployed in virtual private clouds (VPCs).
  • The IP addresses of endpoint groups associated with each GA instance must be globally unique and not conflict with those of other GA instances.
