AWS Global Accelerator imposes specific quotas on the number of Elastic IP addresses that can be used as endpoints within an endpoint group. By default, you can have up to 10 Elastic IP addresses in an endpoint group that contains only Elastic IP address endpoints. This quota is adjustable, meaning you can request an increase if your architecture requires more than 10 Elastic IP addresses per endpoint group[2][3].
Additional important quota details related to Elastic IP addresses and Global Accelerator include:
- The overall number of endpoint groups per accelerator is limited to 42, and the total number of listeners multiplied by the number of endpoint groups cannot exceed 42[2].
- Elastic IP addresses themselves have a default quota of 5 per AWS Region per account, which is separate from the Global Accelerator quotas. This quota can also be increased by submitting a request via the Service Quotas console[4][5].
- Global Accelerator static IP addresses differ from EC2 Elastic IPs in that Global Accelerator IPs are anycast and can be associated with multiple endpoints across multiple AWS Regions, whereas Elastic IPs are tied to a single resource in a single region[9].
To manage or increase these quotas, you must use the Service Quotas console in the US East (N. Virginia) region (us-east-1), as Global Accelerator service quotas are defined and managed there. However, API operations for Global Accelerator are run in the US West (Oregon) region (us-west-2)[2].
In summary, the key quota for Elastic IP addresses as endpoints in AWS Global Accelerator is 10 per endpoint group by default, with the possibility of requesting a higher limit through AWS support channels. This quota is distinct from the Elastic IP address quota at the EC2 level, which also can be increased separately.
