Amazon S3 introduces account regional namespaces for general purpose buckets

Amazon S3 Account Regional Namespaces

You can now create Amazon S3 general purpose buckets in your own reserved namespace, simplifying bucket creation and management as your data storage needs grow. This feature eliminates the need to find globally unique bucket names and makes 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. 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.

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.

What to do

• Add the new bucket namespace request header when creating buckets.
• Update your AWS CloudFormation templates to include your unique account regional suffix.
• Use SCP and IAM policies to enforce consistent bucket naming practices.
