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 Gateway

S3 File Gateway

  • 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 Gateway

  • 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

  • Uses iSCSI protocol

FSx File Gateway

  • 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 Appliance

  • Storage Gateway requires on-premises virtualization. If you don’t 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
