Regional and Zonal endpoints for directory buckets in an Availability Zone

To access your objects and directory buckets stored in S3 Express One Zone, you use gateway VPC endpoints. Directory buckets use Regional and Zonal API endpoints. Depending on the Amazon S3 API operation that you use, either a Regional or Zonal endpoint is required. There is no additional charge for using gateway endpoints.

Bucket-level (or control plane) API operations are available through Regional endpoints and are referred to as Regional endpoint API operations. Examples of Regional endpoint API operations are CreateBucket and DeleteBucket.

When you create directory buckets that are stored in S3 Express One Zone, you choose the Availability Zone where your bucket will be located. You can use Zonal endpoint API operations to upload and manage the objects in your directory bucket.

Object-level (or data plane) API operations are available through Zonal endpoints and are referred to as Zonal endpoint API operations. Examples of Zonal endpoint API operations are CreateSession and PutObject.
