Which AWS product lets an organization use file protocols (for example, NFS) to read and write objects in Amazon S3?

AWS Storage Gateway file gateway allows on-premises applications to access Amazon S3 using standard file protocols like NFS (Network File System) and SMB (Server Message Block). It translates file operations into S3 object requests, enabling seamless integration for file-based workloads. Amazon FSx for Lustre is a high-performance file system for compute-intensive workloads, not primarily for S3 integration via file protocols. AWS Storage Gateway volume gateway provides block storage to on-premises applications, not file-level access to S3. Amazon EFS is a fully managed, scalable NFS file system for EC2 instances, not designed for on-premises access to S3 objects.
