An on-premises app generates files that must stay locally accessible with low latency while tiering seamlessly to cloud storage with NFS/SMB access. Which hybrid storage pattern fits?
A.S3 bucket with lifecycle policies
Lifecycle tiers move data away — no local low-latency access.
B.AWS Storage Gateway File Gateway — local cache backed by S3
Correct. Local cache + S3 backend is exactly File Gateway.
C.EBS volumes replicated to on-premises
EBS can't attach to on-premises systems.
D.Amazon FSx in the cloud only
FSx is fully cloud-side — no on-prem presence.
Why this answer
File Gateway presents NFS/SMB shares on-premises with a local cache — hot data stays local for low latency while everything lives in S3. Cached volumes in Volume Gateway serve the same role for iSCSI block storage.
