Amazon S3 Files (a managed shared file system over a bucket) and Mountpoint for Amazon S3 map to NFS 3.0 support for Blob Storage and BlobFuse2. Azure has no managed file-system layer over Blob comparable to S3 Files.
- Semantics. S3 Files provides full file-system semantics with a managed high-performance layer and two-way sync to the bucket. Mountpoint, BlobFuse2, and NFS 3.0 on Blob are thinner layers that aren't fully POSIX (for example, renames aren't atomic in BlobFuse2).
- Where it mounts. S3 Files mounts on EC2, Lambda, EKS, and ECS. NFS 3.0 on Blob mounts from Linux clients in Azure or on premises over a private network. BlobFuse2 and Mountpoint are client-side FUSE drivers on Linux.
- Prerequisites. NFS 3.0 on Blob needs the hierarchical namespace. BlobFuse2 works with flat or hierarchical accounts.
