    Global Accelerator:Add and manage endpoint groups and endpoints for a basic GA instance

    Last Updated:Jan 30, 2024

    This topic describes how to add an endpoint group to a basic Global Accelerator instance.

    Background information

    Each endpoint group is associated with a specific region. Basic Global Accelerator instances distribute network traffic to endpoints in endpoint groups based on the associated regions.

    The following table describes the endpoint types supported by basic GA instances.Global Accelerator

    Endpoint deployment

    Connection type

    Endpoint type

    Endpoint

    On Alibaba Cloud

    Private connection

    ENI

    Elastic network interface (ENI)

    Only secondary ENIs are supported.

    CLB

    Classic Load Balancer (CLB) instance

    Only CLB instances that are deployed in virtual private clouds (VPCs) are supported.

    NLB

    Network Load Balancer (NLB) instance

    Only internal-facing NLB instances are supported.

    ECS

    Elastic Compute Service (ECS) instance

    Limits

    • You can add only one endpoint group. By default, you can add up to 200 endpoints.

      If you want to add more endpoints, you can increase the gaplus_quota_basic_endpoint_limit quota on the Quota Management page. For more information, see the "Adjust quotas" section of the Manage GA quotas topic.

    • The following endpoint types are supported: secondary ENIs, CLB instances in VPCs, internal-facing NLB instances, and Elastic Compute Service instances. The ENIs, CLB instances, NLB instances, and ECS instances cannot be associated with EIP.

    Note

    • If your basic GA instance was created after August 1, 2023, you can create multiple accelerated IP addresses in an acceleration region and specify internal-facing Network Load Balancer (NLB) instances as endpoints. If your basic GA instance was created before August 1, 2023 and you want to use the preceding features, contact your account manager to upgrade your GA instance.

    • If your Global Accelerator instances were created before August 1, 2023, the following limits apply:

      • You can add only one acceleration area and one acceleration region to each GA instance.

      • You can add only one endpoint group and one endpoint to each GA instance.

      • You cannot specify an NLB instance as an endpoint.

      • You do not need to add an accelerated IP address or associate an accelerated IP address with an endpoint.

    Prerequisites

    • A basic Global Accelerator instance is created. For more information, see Create a basic GA instance.

    • A basic bandwidth plan is created and associated with the GA instance if the GA instance uses the pay-by-bandwidth bandwidth metering method.

    • An application is deployed as an endpoint to receive requests that are forwarded by Global Accelerator. For more information about how to create different types of endpoints, see the following topics:

    • Enterprise real-name verification is completed if the bandwidth metering method of your basic Global Accelerator instance is pay-by-data-transfer and your business involves cross-border data transmission between regions in the Chinese mainland and regions outside the Chinese mainland including China (Hong Kong), China (Macao), and China (Taiwan). For more information, see How do I perform real-name verification?

      Endpoint

      Backend Service

      Client requests are routed to endpoints. To add an endpoint, specify the endpoint type and a backend instance.

      Valid values: ENI, CLB, NLB, and ECS.

      Note

      • Only CLB instances that are deployed in VPCs and secondary ENIs are supported.

      • CLB instances, NLB instances, ECS instances, and ENIs that are associated with elastic IP addresses (EIPs) are not supported.

      Select Node

      Select the private IP addresses that function as endpoints.

      1. Select the private IP address that you want to use in the Private IP Address column.

        • If the endpoint type is ENI, you can select the primary private IP address or secondary private IP addresses of the ENI.

        • If the endpoint type is NLB, you can select the private IP addresses in different zones of the NLB instance.

        • If the endpoint type is CLB, you do not need to select a private IP address.

        • If the endpoint type is ECS, you can select the primary private IP address or secondary private IP addresses of the primary ENI of the ECS instance.

      2. (Optional) In the Node Name (Optional) column, specify the name of the endpoint.

      3. (Optional) In the Accelerated IP Address (Optional) column, select the accelerated IP address that you want to associate with the endpoint.

        If no accelerated IP addresses are available, click Add Accelerated IP Address on the right side to add an accelerated IP address.

        • If no idle accelerated IP addresses are available

          When the message "The IP address is added" appears in the bubble below Add Accelerated IP Address, click Use IP or select the accelerated IP address from the Accelerated IP Address drop-down list.

        • If no acceleration areas are available

          1. In the No acceleration area is available message, click Add Acceleration Area.

    Operation

    Description

    Modify the name of an endpoint group

    1. On the Endpoint Group tab, find the endpoint group that you want to manage. In the Endpoint Group ID/Name column, move the pointer over the right side of the endpoint group name and click编辑.

    2. In the dialog box that appears, modify the name of the endpoint group and click OK.

    Disassociate an accelerated IP address from an endpoint

    After you disassociate an accelerated IP address from an endpoint, the status of the accelerated IP address changes to Idle. When the number of idle accelerated IP addresses reaches the upper limit (10 by default), you cannot disassociate an accelerated IP address from an endpoint.

    1. On the Endpoint Group tab, find the endpoint from which you want to disassociate an accelerated IP address and click Disassociate in the Actions column.

    2. In the message that appears, click Unbind.

    Delete an endpoint

    1. On the Endpoint Group tab, find the endpoint that you want to delete and click Delete in the Actions column.

    2. Delete the endpoint based on the status of the IP address that is associated with the endpoint.

      • When the IP Status of the endpoint is Idle

        In the message that appears, click Delete.

      • When the IP Status of the endpoint is Associated

        In the dialog box that appears, select Delete Endpoint Only or Delete Accelerated IP Addresses Bound to Endpoint, and then click Delete.

    Delete an endpoint group

    Warning

    You can delete an endpoint group. After you delete an endpoint group, Global Accelerator no longer provides acceleration services for the endpoint group.

    Before you delete an endpoint group, take note of the following items:

    • You cannot delete an endpoint group that has an endpoint whose IP Status is Associated. You must first disassociate the IP address from the endpoint.

    • If the IP Status of all endpoints in an endpoint group is Idle, you can delete the endpoint group. The system also deletes all endpoints in the endpoint group at the same time.

    1. On the Endpoint Group tab, find the endpoint group that you want to delete and click Delete in the Actions column.

    2. In the Delete Endpoint Group message, click OK.
