Networking for directory buckets
To access directory buckets and objects inside, you use Regional and Zonal API endpoints that are different from the standard Amazon S3 endpoints. Depending on the S3 API operation that you use, either a Zonal or Regional endpoint is required. For a complete list of API operations by endpoint type, see Differences for directory buckets.
You can access both Zonal and Regional API operations through gateway virtual private cloud (VPC) endpoints.
The following topics describe the networking requirements for accessing S3 Express One Zone by using a gateway VPC endpoint.
Endpoints
You can access directory buckets and objects inside from your VPC by using 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 a directory bucket, you choose a single Zone (Availability Zone or Local Zone) where your
directory bucket will be created. After you create a directory bucket, 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.
For more information about the endpoints and the locations that support directory buckets in Availability Zones, see Endpoints for directory buckets in Availability Zones.
For more information about the endpoints and the locations that support directory buckets in Local Zones, see Enable accounts for Dedicated Local Zones.
Configuring VPC gateway endpoints
To configure gateway VPC endpoints for access directory buckets in Availability Zones, see Configuring VPC gateway endpoints.
To configure gateway VPC endpoints for access directory buckets in Local Zones, see Private connectivity from your VPC.
