1To ensure that resources are distributed across the Availability Zones for these regions, they may differ for each AWS account. You can run aws ec2 describe-availability-zones --region $REGION to be sure which ones are available to you.
2The US GovCloud regions are only available to official U.S. government agencies and organizations.
3The China regions are only available to AWS in China accounts.
You can download a JSON file with all the region data here.
Run ./regions.sh to auto-generate data files for each SDK when the data in regions.json changes.
