AWS Storage Gateway
Bridging the gap between on-premises environments and virtually unlimited cloud storage.
The Core Ingredients
Virtual/Hardware Appliance
Deployed as a VM (VMware, Hyper-V, KVM) or a dedicated hardware device on-site.
Standard Protocols
Uses industry-standard protocols like NFS, SMB, iSCSI, and iSCSI-VTL for seamless integration.
Local Cache
Maintains a low-latency local disk buffer for frequently accessed data sets.
Secure Link
Data is encrypted in transit via SSL/TLS and at rest using AWS KMS keys.
How It Works: Three Specialized Gateways
Data flows from your data center to AWS via optimized paths
On-Premises Data Center
S3 File Gateway
NFS / SMB Interface
Stores files as objects in Amazon S3. Perfect for backups and cloud-native workloads.
Volume Gateway
iSCSI Block Storage
Provides EBS-backed block volumes. Cached (cloud-primary) or Stored (local-primary) modes.
Tape Gateway (VTL)
iSCSI-VTL Interface
Replaces physical tapes with virtual tapes in S3 Glacier. Cost-effective long-term archiving.
