Storage Gateway
- Bridge between on-premises data and S3 for Hybrid Cloud
- Not suitable for one-time sync of large amounts of data (use DataSync instead)
- Optimizes data transfer by sending only changed data
Types of Storage Gatewayβ
S3 File Gatewayβ
- Used to expand on-premise NFS by leveraging S3
- Configured S3 buckets are accessible on premises using the NFS and SMB protocol
- Data is cached at the file gateway for low latency access
- Can be mounted on many servers on-premises
- Integrated with Active Directory (AD) for user authentication
Volume Gatewayβ
- Used for on-premise storage volumes
- Uses iSCSI protocol
- Two kinds of volumes:
- Cached volumes: storage extension using S3 with caching at the volume gateway
- Stored volumes: entire dataset is on premise, scheduled backups to S3 as EBS snapshots
Tape Gatewayβ
- Used to backup on-premises data using tape-based process to S3 as Virtual Tapes
- Uses iSCSI protocol
FSx File Gatewayβ
- Used to expand on-premise Windows-based storage by leveraging FSx for Windows
- Windows native compatibility (SMB, NTFS, Active Directory)
- Data is cached at the file gateway for low latency access
Storage Gateway - Hardware Applianceβ
- Storage Gateway requires on-premises virtualization. If you donβt have virtualization available, you can use a Storage Gateway - Hardware Appliance. It is a mini server that you need to install on-premises.
- Does not work with FSx File Gatway
