What Is Global Accelerator?
Global Accelerator allows users around the world to access cloud applications faster through anycast 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.
Components
- Global accelerator: an instance that routes traffic over the Huawei backbone network to accelerate your access to applications. You can create a global accelerator and select the acceleration area where you would like to use the global accelerator. The system will assign an anycast IP address for access from the nearest access point. When a client sends a request, the request will first go to the nearest access point, then to the Huawei backbone network, and finally to the optimal endpoints.
- 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 area to improve application performance for your users.
- Listener: checks requests from clients based on the protocol and port you have configured and routes the requests to the optimal endpoint in the associated endpoint group. Each listener can have one endpoint group associated in each region.
- Endpoint group: a collection of endpoints that receive traffic from the associated listener. Each endpoint group can include one or more endpoints in a given region.
- Endpoint: an endpoint is a destination to which requests are routed. You can add EIPs, ECSs, load balancers, custom EIPs, IP addresses, or custom domain names as endpoints.
- EIPs, ECSs, load balancers, and custom EIPs for accelerated access to servers deployed on Huawei Cloud.
- IP addresses or custom domain names of servers on a third-party cloud, or servers in an on-premises data center.
