How Global Accelerator Works

The Huawei backbone network used by Global Accelerator is like an expressway network that connects countries around the world. An access point is like an expressway entrance. An acceleration area is a country or geographic region where an access point is deployed. A region is like an exit where you leave an expressway. You can access an application using an EIP over the Internet, which is like driving on a common road. Alternatively, you can access the application over the Huawei backbone network from the nearest access point. This is where Global Accelerator is used. It provides an anycast IP address that allows you to access the application faster.

Suppose you have an application deployed in Shanghai and you use Global Accelerator to accelerate access from users around the globe. Users in Singapore can access the application faster over the Huawei backbone network from the Singapore access point. However, there is no access point in Malaysia. Users in Malaysia can access your application over the Huawei backbone network from the Singapore access point.

Global Accelerator can also accelerate access to an IP address that is not used on Huawei Cloud. You only need to select the region nearest to this IP address. If your application is deployed in your on-premises data center in Wuxi, you can select the Shanghai region nearest to Wuxi. In this way, users in Singapore can access your application from the Singapore access point. Access requests are then transmitted to Shanghai over the Huawei backbone network and finally to Wuxi data center over the public network.
