AWS Storage Gateway is a hybrid storage service that enables your on-premises applications to seamlessly use AWS cloud storage. You can use the service for backup and archiving, disaster recovery, cloud bursting, storage tiering, and migration. Your applications connect to the service through a gateway appliance using standard storage protocols, such as NFS and iSCSI. The gateway connects to AWS storage services, such as Amazon S3, Amazon Glacier, and Amazon EBS, providing storage for files, volumes, and virtual tapes in AWS. The service includes a highly-optimized data transfer mechanism, with bandwidth management, automated network resilience, and efficient data transfer, along with a local cache for low-latency on-premises access to your most active data.
AWS Storage Gateway Benefits
- Optimized Transfers
- Cloud Scale
- Durable and Secure
AWS Storage Gateway Features
Connect as File Storage
The File Gateway configuration offers on-premises servers and applications a network file share via an NFS connection. File data is cached on the File Gateway for local performance and converted to objects stored in Amazon S3. You can protect and archive your objects through native AWS tools such as lifecycle policies, versioning and cross-region replication.
Connect as a Virtual Tape Library
The Tape Gateway configuration replaces backup tapes and tape automation equipment with local disk and cloud storage. Your existing backup and recovery software writes native backup jobs to virtual tapes stored on the Tape Gateway. Virtual tapes can be migrated into Amazon S3 and eventually archived into Amazon Glacier for the lowest cost. Data is accessed through your backup application and the backup catalog maintains complete visibility for all backup jobs and tapes.
Connect as Block Storage
The Volume Gateway configuration connects to on-premises servers and applications as a local disk using iSCSI. Data in these volumes can be transferred into Amazon S3 cloud storage and accessed through the Volume Gateway. Store data locally for the highest performance (with snapshot backups to the cloud), or blend latency and scale by storing frequently-accessed data locally with "cooler" data in the cloud (with snapshots and clones for protection as well).
Transfer Data Into and Out of the AWS Cloud
Amazon EFS provides a file system interface and file system access semantics (such as strong data consistency and file locking). Amazon EC2 instances mount Amazon EFS file systems via the NFSv4 protocol, using standard operating system mount commands. You can also mount Amazon EFS file systems on your on-premises datacenter servers via the NFSv4 protocol when connected to your Amazon VPC with AWS Direct Connect.
Storage Gateway automatically buffers on-premises data and efficiently moves it into (and out of) cloud storage services. This reduces the time and cost of moving data between your site and the AWS Cloud. Optimizations such as multipart management, delta transfers, bandwidth throttling, and bandwidth scheduling are standard for all interfaces.
