Amazon S3 introduces account regional namespaces for general purpose buckets

You can now create Amazon S3 general purpose buckets in your own reserved namespace, eliminating the need to find globally unique bucket names and making it easier to build workloads that utilize a bucket per customer, team, or dataset. With account regional namespaces, you can create predictable bucket names across multiple AWS Regions with assurance that the names you want will always be available for you to use.

Account regional namespaces help simplify bucket creation and management as your data storage needs grow in size and scope. To get started, add the new bucket namespace request header when creating buckets through the CreateBucket API or by updating your AWS CloudFormation templates to include your unique account regional suffix in the requested name. Additionally, cloud security teams can use service control policies (SCP) and IAM policies to enforce that users only create buckets in their account regional namespace, helping teams enforce consistent bucket naming practices across their enterprise.

Account regional namespaces for S3 general purpose buckets are now available in 37 AWS Regions including the AWS China and AWS GovCloud (US) Regions at no additional cost through the AWS Management Console, S3 REST API, AWS CLI, AWS SDK, and AWS CloudFormation.
