A shared-bandwidth Global Acceleration instance provides the Internet bandwidth only and no public IP. You can add multiple Elastic IP Addresses (EIPs) to a shared-bandwidth instance and then bind these EIPs to the backend servers to be accelerated.

Create Instance

Before configuring acceleration services, you must create a Global Acceleration instances. By sharing the instance bandwidth, the shared-bandwidth instance help you save Internet cost. For more information, see Step 1. Create a Global Acceleration instance.

Add an EIP

No public IP is provided for shared-bandwidth instances. You must add an EIP to it to accelerate the Internet access. For more information, see Add an EIP.

Bind a backend service

After creating a shared-bandwidth instance and binding EIPs, you can bind the EIPs to the backend servers. Shared-bandwidth instances support adding SLB instances of the VPC network and ECS secondary ENI. Up to 50 EIPs can be added to a shared-bandwidth instance and each EIP can be bound to a backend service. For more information, see Bind a backend service.
