Developing with S3 Express One Zone

Amazon S3 Express One Zone is the first S3 storage class where you can select a single Availability Zone with the option to co-locate your object storage with your compute resources, which provides the highest possible access speed. With S3 Express One Zone storage class, you use S3 directory buckets to store your data. Each directory bucket uses the S3 Express One Zone storage class to store objects in a single Availability Zone that you can select when you create the bucket.

After you've created your directory bucket, you can then immediately begin very low-latency reads and writes. You can communicate with your directory bucket by using an endpoint connection over a virtual private cloud (VPC), or you can use Zonal and Regional API operations to manage your objects and directory buckets. You can also use S3 Express One Zone storage class through the Amazon S3 console, AWS Command Line Interface (AWS CLI), AWS SDKs, and the Amazon S3 REST API.

The Amazon S3 Express One Zone storage class is designed for 99.95 percent availability within a single Availability Zone and is backed by the Amazon S3 Service Level Agreement. With S3 Express One Zone, your data is redundantly stored on multiple devices within a single Availability Zone. S3 Express One Zone is designed to handle concurrent device failures by quickly detecting and repairing any lost redundancy. If the existing device encounters a failure, S3 Express One Zone automatically shifts requests to new devices within an Availability Zone. This redundancy helps ensure uninterrupted access to your data within an Availability Zone.
