Storage Gateway

AWS Storage Gateway
-         https://docs.aws.amazon.com/storagegateway/latest/userguide/StorageGatewayConcepts.html

-         a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage.
-         customer applications connect to the service through a virtual machine or hardware gateway appliance using standard storage protocols, such as NFS, SMB, and iSCSI. The gateway connects to AWS storage services, such as Amazon S3 (as block storage!), Amazon S3 Glacier, Amazon S3 Glacier Deep Archive, Amazon EBS, and AWS Backup, providing storage for files, volumes, snapshots, and virtual tapes in AWS
-         Modes:
          §  File gateway - Store files as objects in Amazon S3, with a local cache for low-latency access to your most recently used data

          §  Create and configure your file share and associate that share with your Amazon S3 bucket. Doing this makes the share accessible by clients using either the NFS or SMB protocol. Files written to a file share become objects in Amazon S3, with the path as the key. There is a one-to-one mapping between files and objects, and the gateway asynchronously updates the objects in Amazon S3 as you change the files

          §  Volume gateway - Block storage in Amazon S3 with point-in-time backups as Amazon EBS snapshots.
                 §  Cached (volume gateway) – store data on AWS; keep most frequently asked pieces of data on the gateway
                 §  Stored (volume gateway) – the gateway saves data to local on-premise locations AND sends a snapshot of data onto AWS

                 §  VTL – Virtual Tape Library (tape gateway) - The gateway will interface with on-premise tape back up devices (not on AWS)
