AWS storage gateway provides on-premises application with access to virtually unlimited cloud storage.
- AWS storage gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage.
- AWS storage gateway can be used to simplify storage management & to reduce costs for key hybrid cloud storage use cases.
- Which include moving backup to the cloud using on premises file shares backed by cloud storage & providing low latency access to data in AWS for on-premises application.
Storage Gateway Types
There are three types of storage gateways:
- File Gateway
- Tape Gateway
- Volume Gateway
File Gateway: File gateway presents a file interface that enables you to store files as objects in S3 using the industry-standard NFS & SMB file protocols and access those file via NFS & SMB from your data center amazon EC2 or access those file as objects directly in amazon S3.
Tape Gateway: Tape gateway presents a virtual tape library (VTL) consisting of virtual type drives & a virtual media changer to your backup application using storage industry standard ISCSI protocol.
Volume Gateway: Volume gateway presents your application block storage volume using the ISCSI protocol. Data written to those volumes can be asynchronously backed up as point in the snapshot of your volumes & stored in the cloud as Amazon EBS snapshots.
Key Points:
File Gateway -> Backup Application, Database Backup, & File Share.
Volume cache/Volume gateway -> Application server, migrate to your S3 server.
Tape Gateway -> Backup Application, eg: VM backup, third party backup, backup your data S3 storage.
