Storage Gateway

• Storage Gateway consists of an on-premises software appliance which connects with AWS cloud-based storage to give you a seamless and secure integration between your on-premises IT environment and AWS.

• File Gateway

  • Files stored as objects in S3 buckets

  • Accessed using SMB or NFS mount points

  • To your on-premises systems this appears like a file system mount backed by S3

  • All the benefits of S3: bucket policies, S2 versioning, lifecycle management, replication, etc.

  • Low-cost alternative to on-premises storage

• Volume Gateway

  • Provides cloud backed storage which is accessed using iSCSI protocol

  • 2 different types available:

    • Gateway Stored Volumes

      • The gateway stores all your data locally, so your applications get low latency access to the entire dataset

      • You need your own storage infrastructure as all data is stored locally in your data center

      • Provides durable off-site async backups in the form of EBS snapshots which are stored in S3

    • Gateway Cached Volumes

      • The gateway stores all your data in S3 and caches only frequently accessed data locally

      • You need only enough local storage capacity to store the frequently accessed data

      • Applications still get low-latency access to frequently used data without a large investment in on-premise storage

• Tape Gateway

  • Virtual Tape Library which provides cost effective data archiving in the cloud using Glacier

  • You don't need to invest in your own tape backup infrastructure

  • Integrates with existing tape backup infrastructure - NetBackup, Backup Exec, Veeam, etc. which connect to the VTL using iSCSI

  • Data is stored on virtual tapes which are stored in Glacier and accessed using VTL
