Amazon S3 Express One Zone is a new storage class designed for high-performance applications requiring the lowest latency and highest performance cloud object storage. It offers consistent single-digit millisecond latency, enabling users to accelerate data processing and improve access times. S3 Express One Zone allows data storage in specified availability zones, facilitating co-location of storage and compute resources to reduce latency. This storage class is optimized for workloads with many small objects and can handle hundreds of thousands of requests per second for frequently accessed datasets. It's ideal for accelerating analytics, machine learning, and other high-performance workloads while reducing overall TCO through lower request costs and more efficient use of compute resources. S3 Express One Zone integrates seamlessly with existing Amazon S3 APIs, eliminating the need for managing multiple storage systems for low-latency workloads.
