Add and manage acceleration areas - basic GA instances - Global Accelerator

After you create a basic Global Accelerator instance, add an acceleration area to define where clients enter the Alibaba Cloud acceleration network.

Overview

Clients use accelerated IP addresses to connect to the Alibaba Cloud acceleration network. Supported acceleration areas and regions of Global Accelerator are listed in Acceleration areas and regions supported by basic GA instances.

Acceleration areas of a basic Global Accelerator instance:

Acceleration area and region: Only one acceleration area and one acceleration region per instance.
Acceleration region bandwidth: Depends on the billing method.
- If the billing method is pay-by-data-transfer, you can specify a custom bandwidth for the acceleration region.
- If the billing method is pay-by-bandwidth, bandwidth is capped at the maximum of the associated basic bandwidth plan.
Accelerated IP address: By default, accelerated IP addresses are of the Elastic IP Address (EIP) type and support IPv4 only.
By default, a single basic Global Accelerator instance supports up to 20 accelerated IP addresses. Each IP address can map to a different endpoint. States:
- Bound: The IP address is associated with an endpoint, creating a mapping. Global Accelerator distributes traffic to the backend service based on this mapping.
- Idle: The IP address is not associated with any endpoint. By default, a single basic Global Accelerator instance supports up to 10 idle IP addresses. If this quota is reached, you cannot add more idle IP addresses or disassociate existing ones from endpoints.
To add more accelerated IP addresses or increase the idle IP address quota, increase the gaplus_quota_basic_gaip_limit quota or the gaplus_quota_basic_gaip_idle_limit quota on the Quota Management page. For more information, see the Increase quotas section of the Manage GA quotas topic.

Note

Basic GA instances created after August 1, 2023 support the use of multiple accelerated IP addresses in an acceleration region and private Network Load Balancer (NLB) endpoints. If your basic GA instance was created before this date and you want to use these features, contact your business manager to upgrade the instance.
If your Global Accelerator instances were created before August 1, 2023, the following limits apply:
- Each GA instance supports only one acceleration area and one acceleration region.
- Each GA instance supports only one endpoint group and one endpoint.
- You cannot specify an NLB instance as an endpoint.
- You do not need to add or associate accelerated IP addresses with endpoints.

Add an acceleration area

Prerequisites:

You have created a basic Global Accelerator instance.
For subscription-based GA instances, you must have purchased and associated a basic bandwidth plan.

Log on to the GA console.
In the left-side navigation pane, click Basic Instance.
On the Basic GA Instance page, find the basic Global Accelerator instance that you want to manage and click its ID.
On the instance details page, click the Acceleration Areas tab and then click Add Acceleration Area.

In the Add Acceleration Area dialog box, configure the parameters and click OK.

Parameter	Description
Regions	Select the acceleration region. Area-to-region mappings are documented in Acceleration areas. Note If the client is in a region that is not supported by GA, you can select the nearest acceleration region. Client traffic can enter the Alibaba Cloud acceleration network from the selected acceleration region through the accelerated IP address.
Bandwidth	Set the bandwidth for the acceleration region in Mbps. If the billing method is pay-by-data-transfer, you can specify a custom bandwidth for the acceleration region. Valid values: 2 to 20000. If the billing method is pay-by-bandwidth, bandwidth is capped at the maximum of the associated basic bandwidth plan. Important A low bandwidth cap may cause traffic drops. Plan bandwidth based on your business needs.
Internet Protocol	Select the IP protocol for accessing Global Accelerator. Only IPv4 is supported.
ISP Line Type	Select the ISP line type for accessing Global Accelerator. This parameter is available only for Global Accelerator instances that use the pay-by-data-transfer billing method. BGP (Multi-ISP): BGP (Multi-ISP) provides high-quality BGP lines that cover multiple regions across the globe. It connects to the networks of multiple carriers and automatically selects the optimal route to ensure fast and stable access. All acceleration regions support and use the BGP (Multi-ISP) type by default. BGP Pro: BGP Pro is a premium network line that optimizes traffic from regions outside the Chinese mainland to the Chinese mainland. It improves the quality of international connections. Compared with standard BGP (Multi-ISP) lines, BGP Pro lines provide lower latency when they serve clients in the Chinese mainland (excluding data centers in the Chinese mainland) because they are directly connected to the Chinese mainland through premium carrier networks. Currently, GA supports the BGP Pro type only in the China (Hong Kong) and Japan (Tokyo) regions.

Conditionally required: If your basic Global Accelerator instance is pay-as-you-go (uses the pay-by-data-transfer billing method), an endpoint group already exists, and your service requires cross-border acceleration between the Chinese mainland and other regions or countries, you must complete the following steps in the Enable Cross-border Acceleration dialog box: Read the Compliance Commitments Regarding Cross-border Data Transfers, select Agree to the Preceding Compliance Agreement, and then click Enable.

Important
If your service involves acceleration between regions in the Chinese mainland and regions outside the Chinese mainland, such as China (Hong Kong), China (Macao), and China (Taiwan), or between other countries, make sure that you have completed enterprise real-name registration.

Add an accelerated IP address

After you add an acceleration area and region, add an accelerated IP address. Clients connect to the Alibaba Cloud acceleration network through this IP address.

Log on to the GA console.
In the left-side navigation pane, click Basic Instance.
On the Basic GA Instance page, find the basic Global Accelerator instance that you want to manage and click its ID.
On the instance details page, click the Acceleration Areas tab, and then click Add Accelerated IP Address.
Optional: In the Associate Endpoint dialog box, select an endpoint to bind and click Associate Endpoint.
Note
- Ensure that you have created an endpoint not associated with another IP address. Add and manage endpoint groups and endpoints.
- The system automatically allocates an accelerated IP address. If you skip endpoint selection and click Cancel, the IP address becomes Idle. By default, a single basic Global Accelerator instance can have up to 10 idle IP addresses.

Associate an idle IP with an endpoint

Associating an idle IP address with an endpoint maps them together. Global Accelerator then distributes traffic to the backend service accordingly.

Before you bind an idle IP address to an endpoint, ensure the endpoint exists and is not bound to another IP address. Add and manage endpoint groups and endpoints.

Log on to the GA console.
In the left-side navigation pane, click Basic Instance.
On the Basic GA Instance page, find the basic Global Accelerator instance that you want to manage and click its ID.
On the instance details page, click the Acceleration Areas tab, find the target idle accelerated IP address, and then click Associate Endpoint in the Associate Endpoint column.
In the Associate Endpoint dialog box, select an endpoint to bind and click OK.

Modify acceleration region bandwidth

You can modify the bandwidth of an acceleration region only for basic Global Accelerator instances that use the pay-by-data-transfer billing method.

Log on to the GA console.
In the left-side navigation pane, click Basic Instance.
On the Basic GA Instance page, find the basic Global Accelerator instance that you want to manage and click its ID.
On the instance details page, click the Acceleration Areas tab and then click Modify Bandwidth.
In the Modify Bandwidth dialog box, change the bandwidth of the acceleration region and click OK.
Valid values: 2 to 20000.

More operations

Actions	Description
Disassociate an accelerated IP address from an endpoint	Disassociating an IP address from an endpoint changes its state to Idle. This is blocked if idle IP addresses have reached the quota (default: 10). On the Acceleration Areas tab, find the target accelerated IP address and click Disassociate in the Actions column. In the confirmation dialog box that appears, click UnBind.
Delete an accelerated IP address	On the Acceleration Areas tab, find the target accelerated IP address and click Delete in the Actions column. The deletion steps vary depending on the state of the accelerated IP address. If the accelerated IP address is Idle: In the confirmation dialog box that appears, click Delete. If the accelerated IP address is Bound: In the confirmation dialog box that appears, select Delete Accelerated IP Address Only or Delete Accelerated IP Address and Its Associated Endpoint, and then click Delete.
Delete an acceleration area	Warning Deleting an acceleration area stops Global Accelerator from providing acceleration services for that area. Before you delete an acceleration area: You cannot delete an acceleration area that contains accelerated IP addresses in the Bound state. Disassociate all IP addresses from their endpoints first. If all accelerated IP addresses in an acceleration area are in the Idle state, you can delete the acceleration area directly. The system deletes all idle IP addresses in the area. On the Acceleration Areas tab, find the target acceleration area and click Delete in the Actions column. In the confirmation dialog box that appears, click OK.
