S3 Files (aws.amazon.com)

AWS announced S3 Files, which exposes Amazon S3 buckets through a NFS v4.1+ file system interface. The service automatically syncs file changes back to the underlying S3 objects and lets multiple compute resources access the same data without duplication, using features like ~1 ms latency for active data via EFS-based architecture. AWS says access control, encryption, and monitoring are handled through existing IAM, TLS/S3 encryption options, CloudWatch, and CloudTrail, and the blog includes steps to mount an S3 bucket on EC2.
