Each Global Accelerator (GA) instance is an acceleration service that runs on a global scale. GA provides multiple instance specifications. Each instance specification provides different acceleration capabilities to meet your requirements in different scenarios.

GA简介-中国站

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 can connect to the nearest access point of the Alibaba Cloud global transmission network by sending requests to the accelerated IP address. GA then automatically selects routes to distribute client requests to the optimal endpoints based on the configurations of listeners. This avoids network congestion and reduces network latency. You can specify Elastic Compute Service (ECS) instances, Classic Load Balancer (CLB) instances, Application Load Balancer (ALB) instances, Object Storage Service (OSS) buckets, Alibaba Cloud public IP addresses, custom IP addresses, or custom domain names as the endpoints of GA.

Specifications of GA instances

GA provides multiple instance specifications. Each instance specification provides different acceleration capabilities, as described in the following table.
