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 Pasted image 20230531205741.png

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)
