What Is Global Accelerator?

Global Accelerator allows users around the world to access cloud applications faster through public IP addresses and highly reliable, low-latency, and secure networking services.

As shown in Figure 1, a multinational enterprise has branches all over the world. The Singapore branch has deployed an application on two servers in the CN South-Guangzhou region, and the Hong Kong branch has deployed an application on two servers in the CN-Hong Kong region.

With Global Accelerator, each branch can access their application faster from the nearest access point.

Figure 1 How Global Accelerator works

Components

  • Global accelerator: an instance that routes traffic over the Huawei Cloud backbone network to accelerate your access to applications. You can create a global accelerator and select where you would like to use the global accelerator. The system will allocate an anycast IP address to each area where the global accelerator will be used. The clients can access the cloud from the nearest access points, and their traffic will then be routed to the optimal endpoints through the Huawei Cloud backbone network.
  • Acceleration area: a location where a global accelerator is used in or outside the Chinese mainland. You can configure the location where your users are located as an acceleration region to improve application performance for your users.
  • Listener: checks requests from clients based on the protocol and port you configure and routes the requests to the optimal endpoint in the associated endpoint group. Each listener can have one endpoint group associated in each acceleration area.
  • Endpoint group: a collection of endpoints that receive traffic from the associated listener. Each endpoint group can include one or more endpoints in a specific region.
  • Endpoint: a resource that traffic is directed to. Currently, endpoints can only be EIPs. You can assign a weight to each endpoint. The global accelerator will distribute traffic to the endpoints based on their weights.
