The new 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. Using Amazon S3 Express One Zone with Mountpoint for Amazon S3 accelerates file-based applications that make random data access requests by up to 6x compared to S3 Standard. This speeds up machine learning training jobs for vision models, completing them faster and reducing compute costs. Additionally, with S3 Express One Zone’s integrations with Mountpoint for Amazon S3 and big data platforms like Amazon EMR, you can prepare your training data using Amazon EMR and run training jobs using Mountpoint on the same dataset, which simplifies your architecture.
