In one sentence
Storage Gateway preserves NFS/SMB, iSCSI, or virtual-tape workflows on premises and bridges them to AWS.
Core purpose
- S3 File Gateway maps local NFS/SMB files to S3 objects.
- Volume Gateway exposes iSCSI volumes and uses snapshots for backup and recovery.
- Tape Gateway replaces physical tape infrastructure with virtual tapes.
Exam focus
- Files to S3 point to File Gateway; local block volumes to Volume Gateway; tape replacement to Tape Gateway.
- DataSync favors bulk transfer, Direct Connect/VPN provide networking, and DRS recovers complete servers.
- Plan local cache, bandwidth, permissions, encryption, and recovery procedures.
Common misconceptions
- Storage Gateway is not a dedicated network connection.
- File Gateway targets S3 objects, but S3 itself is still not a normal file system.
Key takeaway
Files → File Gateway; volumes → Volume Gateway; tapes → Tape Gateway.
