Storage Gateway¶
TLDR¶
Can be used for a hybrid cloud setup, where data is produced on premise and synced to AWS.
Use cases¶
- long term migrations
- security
- compliance
- general IT strategy (hybrid cloud)
- tiered storage
- backup and restore
- disaster recovery
- on-premises cache & low-latency file access
Gateway Types¶
S3 File Gateway¶
- Configured S3 Buckets are accessible using the NFS or SMB Protocol
- Translates save file request to HTTP request to S3
- Most recently used data is cached in file gateway, so it doesn't have to be fetched from AWS.
- Can use all tiers except Glacier.
- Bucket access using IAM roles for each file gateway.
- SMB Protocol has integration with Active directory (AD) for user authentication.
FSx File Gateway¶
- Native access to FSxWindowsFileServer
- Local cache for frequently accessed data
- Windows native compatibility (SMB, NTFS, AD)
- Group file shares and home directories
Volume Gateway¶
- Block Storage using iSCSI backed by S3
- backed by EBS snapshots – can be used to restore on-premises volumes.
- Cached volumes: low latency access to most recent data.
- Stored volumes: entire dataset is on-premise, scheduled back-ups to S3
Tape Gateway¶
- uses Virtual Tape library (VTL)
- back data using existing tape-based processes (and iSCSI interface)
- for backup processes using physical Tapes
- can send directly into S3 Glacier
Hardware appliance¶
- useful when you don't have any VM for the storage gateway
- Can be bought from amazon.com
- Is a hardware which will be your gateway (like a firewall)
