AWS Storage Gateway
The AWS Storage Gateway service seamlessly enables hybrid storage between on-premises storage environments and the AWS Cloud. It combines a multi-protocol storage appliance with highly efficient network connectivity to Amazon cloud storage services, delivering local performance with virtually unlimited scale. Customers use it in remote offices and datacenters for hybrid cloud workloads, backup and restore, archive, disaster recovery, and tiered storage.
The Storage Gateway virtual appliance connects directly to your local infrastructure as a file server, as a volume, or as a virtual tape library (VTL). This seamless connection makes it simple for organizations to augment existing on-premises storage investments with the high scalability, extreme durability and low cost of cloud storage.
Connect as a File Server
The file interface offers on-premises servers and applications access to Storage Gateway as a network file share. Data is cached for local performance. Once in Amazon S3, data is accessible as objects in S3. You can protect your data in S3 through native tools like versioning and cross-region replication.
Connect as a Local Disk
The volume interface presents the Storage Gateway to on-premises servers and applications as a local disk. Data in these volumes can be transferred into Amazon S3 cloud storage and accessed through the Storage Gateway service. 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.
Connect as a Virtual Tape Library (VTL)
The tape interface 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 Storage Gateway. Virtual tapes can be migrated into Amazon S3 and eventually archived into Amazon Glacier for the lowest cost. Data is accesssed through your backup application and the backup catalog maintains complete visibility for all backup jobs and tapes.
Transfer Data Into and Out of the Cloud
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.
