Amazon S3 Express One Zone is designed for high-performance, low-latency object storage. It provides single-digit millisecond access times, making it ideal for real-time applications, big data analytics, and machine learning workloads. ❌ B. S3 Standard – While S3 Standard is fast, it is not explicitly optimized for the lowest latency like S3 Express One Zone. ❌ C. S3 Glacier Flexible Retrieval – Designed for archival storage, takes minutes to hours to retrieve data. ❌ D. S3 Glacier Instant Retrieval – Provides millisecond access but is optimized for archival workloads, not high-performance storage.
