This topic provides answers to some frequently asked questions about endpoint groups of Global Accelerator (GA).
Can I use GA if the region where my endpoints are deployed is not supported by GA?
How do I view the endpoint group IP addresses of a GA instance?
Can I use GA if the region where my endpoints are deployed is not supported by GA?
Yes.
You can select the region that is nearest to your endpoints when you configure the endpoint group. GA forwards requests to the optimal endpoint in the endpoint group.
How do I view the endpoint group IP addresses of a GA instance?
You can view the endpoint group IP addresses in a region in the GA console:
Log on to the GA console.
On the Instances page, find the GA instance that you want to manage and click Configure Listeners in the Actions column.
On the Listeners tab, find the listener that you want to manage and choose
> View Endpoint Group in the Actions column. On the Endpoint Group tab, find the endpoint group that you want to view. The public IP addresses of endpoints in the region where the endpoint group resides are displayed in the Endpoint Public IP Address column.
The system assigns at least four public IP addresses to each endpoint. The number of public IP addresses assigned to an endpoint varies based on the following factors when different billing methods are used:
The volume of traffic if the pay-as-you-go billing method is used. The CIDR blocks or the IP addresses of the endpoint are added or removed based on traffic fluctuation.
You can call API operations to query the public CIDR blocks or IP address of an endpoint. For more information, see ListEndpointGroups and ListEndpointGroupIpAddressCidrBlocks.
The instance specifications if the subscription billing method is used. When you modify the specifications of a GA instance, the public IP addresses of the endpoint may be added or removed.
The added public IP address enters the Available state only after you manually confirm the modified specifications of the GA instance. You can confirm the modified specifications of the GA instance in the GA console or by calling the UpdateAcceleratorConfirm operation.
What endpoint types are supported by GA?
The endpoint types that are supported by GA vary based on where your endpoint is deployed.
Instance type | Deployment location | Endpoint type |
Standard GA instance | Outside Alibaba Cloud |
|
On Alibaba Cloud |
| |
Basic GA instance | On Alibaba Cloud |
|
If your standard GA instance does not support ALB instances, ECS instances in VPCs, CLB instances in VPCs, NLB instances, or ENIs as endpoints, the GA instance may be using an earlier version. Contact your account manager to upgrade your GA instance. If you have the permissions to upgrade GA instances, you can upgrade your GA instance. For more information, see Upgrade a GA instance.
Basic GA instances support the following endpoint types: secondary elastic network interfaces (ENIs), Classic Load Balancer (CLB) instances in virtual private clouds (VPCs), internal-facing Network Load Balancer (NLB) instances, and Elastic Compute Service (ECS) instances. The preceding resources cannot be associated with elastic IP addresses (EIPs).Elastic IP Address (EIP)
