AWS Storage Gateway is a fully managed, hybrid-cloud storage service that provides on-premises access to virtually unlimited cloud storage.

Gateway Types

  1. Amazon S3 File Gateway
    • This allows you to bridge your local environment with Amazon S3. It provides on-premises applications with access to virtually unlimited cloud storage through familiar file protocols.
    • It appears to your computer as a standard file server.
      • meaning, when files are written to this server, they are automatically uploaded to Amazon S3.
  2. Volume Gateway
    • It functions as a bridge between your on-premises infrastructure and AWS Cloud Storage by presenting your cloud data as iSCSI volumes that can be mounted by applications
    • How is this different from S3 File Gateway?
      • Volume Gateway presents cloud storage as block storage volumes rather than file shares
  3. Tape Gateway
    • provides an interface that works with existing tape backup software, making the transition from physical tapes to cloud storage seamless.
