This topic describes the service of Global Accelerator (GA). Each GA instance is an acceleration service running on a global scale. GA provides six types of GA instance specifications with different acceleration capabilities to help you meet the diverse needs in different scenarios.
After you create a GA instance, you must configure a bandwidth plan and set acceleration areas. GA assigns an accelerated IP address to each acceleration region in an acceleration area. Clients from an acceleration region can connect to the nearest access point of the Alibaba Cloud global network through the accelerated IP address. GA then automatically selects routes to distribute client requests to the optimal endpoints to avoid network congestion and reduce network latency. Endpoints can be IP addresses or domain names of origin servers.
