How Can I Use Global Accelerator to Enable European Users to Access the Applications Deployed in or Outside the Chinese Mainland (Excluding Europe) Faster?

Application Scenario

If you select Chinese mainland or Outside the Chinese mainland for Applicability when creating a global accelerator, you cannot use it to accelerate access from European users. If your application is deployed in or outside the Chinese mainland (excluding Europe) and you want users in Europe to access your application faster, you can create global accelerators in an Open Cloud Service Alliance region (for example, EU-Dublin) and select a region in or outside the Chinese mainland (excluding Europe) for the endpoint group. Similarly, if your application is deployed in Ireland and you want users in the Chinese mainland or Asia Pacific to access your application faster, you need to switch to the Huawei Cloud International website from an Open Cloud Service Alliance region for creating global accelerators.

In this example, your application is deployed in the CN East-Shanghai1 region. To accelerate access from countries in Latin America, Africa, Asia Pacific, and Europe, you need to create two global accelerators.

Figure 1 Example scenario

Constraints

To switch between the Huawei Cloud International website and the Huawei Cloud European website for creating global accelerators, you need to submit a service ticket to obtain Cloud Alliance account permissions.

Operation Process

Figure 2 Operation process

Procedure

1. Create a global accelerator on the console of the Huawei Cloud International website.

   Set Applicability to Outside the Chinese mainland (for users in Asia Pacific, Africa, and Latin America, excluding Europe) and select CN East-Shanghai1 as the region of the endpoint group.

   For details, see Creating a Global Accelerator.

2. Create a global accelerator on the console of the Huawei Cloud European website.
   1. On the console homepage, select EU-Dublin from the region list.
   2. Create a global accelerator. Set Applicability to Europe (for users in Europe) and select CN East-Shanghai1 as the region of the endpoint group.

3. Configure DNS intelligent resolution.

   You need to configure DNS region lines to resolve the domain name for users in different regions:

   • Users in Europe: The domain name is mapped to the anycast IP address assigned to the global accelerator created in step 2.
   • Users outside the Chinese mainland (such as Asia Pacific, Latin America, and Africa): The domain name is mapped to the anycast IP address assigned to the global accelerator created in step 1.
   • Users in the Chinese mainland: The domain name is mapped to the EIP used by the application deployed in CN East-Shanghai1.
