Limits on Global Accelerator - Global Accelerator - Alibaba Cloud Documentation Center

This topic describes the configuration limits of Global Accelerator (GA) and the default quotas and quota adjustment instructions for different types of GA resources.

Limits on instance types

The following table describes the limitations of standard GA instances and basic GA instances:

Pay-as-you-go standard GA instances support selecting accelerated IP address types, including Elastic IP Address and Anycast Elastic IP Address types. Subscription standard GA instances only support the Elastic IP Address type.
For subscription standard GA instances, you need to select the appropriate instance specification as needed and associate a basic bandwidth plan.
Subscription basic GA instances can only be associated with basic bandwidth plans that provide standard or premium bandwidth.
The accelerated IP address type for basic GA instances is set to Elastic IP Address by default and does not support the Anycast Elastic IP Address type.

Note

GA instances with Large III or higher specifications are unavailable by default. To use these instances, contact your account manager.

Acceleration areas supported by GA	China North, China South, China East, China Southwest, Asia Pacific, Europe, North America, South America, and Middle East Note You can also specify regions in each acceleration area. For more information about the mapping between areas and regions, see Acceleration areas and regions for standard GA instances and Acceleration areas and regions for basic GA instances.		Not adjustable
Types of accelerated IP addresses supported by GA	Elastic IP Address Anycast Elastic IP Address Note For more information about accelerated IP address types, see Accelerated IP addresses.	Elastic IP Address (default)	Cannot be modified
The maximum number of accelerated IP addresses that can be added to each GA instance	Determined by the billing method and accelerated IP address type: Pay-as-you-go If the accelerated IP address type is Elastic IP Address: Two EIPs are allocated to each acceleration region. If the accelerated IP address type is Anycast Elastic IP Address: GA provides two Anycast EIPs across multiple regions worldwide. Subscription The number of accelerated IP addresses is equal to the number of acceleration regions. GA allocates a separate EIP to each acceleration region.	20	You can increase quotas in Quota Center or on the Quota Management page. For more information, see Increase a quota.

The maximum number of endpoint groups that can be added to each GA instance	Determined by the billing method, along with the number and types of listeners that you add to a GA instance: Pay-as-you-go: For each TCP, UDP, HTTP, or HTTPS listener: two endpoint groups. Subscription: For each TCP or UDP listener: two endpoint groups. For each HTTP or HTTPS listener: one endpoint group.	1	You can request more endpoint groups only for TCP or UDP listeners.
