The Amazon S3 Express One Zone storage class is purpose-built to deliver the fastest cloud object storage for performance-critical applications that demand consistent single-digit millisecond request latency. S3 Express One Zone can improve data access speeds by 10x and reduce request costs by 50% compared to S3 Standard. It enables workloads such as machine learning training, interactive analytics, and media content creation to achieve single-digit millisecond data access speed with high durability and availability.

S3 Express One Zone uses a new bucket type, S3 directory buckets, to support hundreds of thousands of requests per second and uses purpose-built hardware and software optimized for low latency. While you have always been able to choose a specific AWS Region to store your S3 data, with S3 Express One Zone you can now select a specific AWS Availability Zone within an AWS Region to store your data. You can choose to co-locate your storage and compute resources in the same Availability Zone to further optimize performance, which helps lower compute costs and run workloads faster. You can use S3 Express One Zone to accelerate your AI/ML and analytics workloads with services such as Amazon SageMaker Model Training, Amazon Athena, Amazon EMR, and AWS Glue Data Catalog. 

S3 Express One Zone is generally available in the US East (N. Virginia), US West (Oregon), Europe (Stockholm), and Asia Pacific (Tokyo) AWS Regions.

Get started with S3 Express One Zone by creating a directory bucket in the S3 console or through the AWS CLI and uploading objects into it. You can use S3 Batch Operations to run copy jobs at scale to fill your directory buckets or automatically import data into your directory buckets from existing buckets.
