What AWS Storage Gateway is

AWS Storage Gateway connects on-premises applications to cloud storage while caching data locally for low-latency access. Its gateway types cover tape, file, and volume workflows: Tape Gateway, Amazon S3 File Gateway, Amazon FSx File Gateway, and Volume Gateway. Applications can use NFS, SMB, iSCSI, or iSCSI-VTL to access AWS storage without modification. S3 File Gateway stores files as Amazon S3 objects, while Tape Gateway presents a virtual tape library compatible with most leading backup applications.

Gateways can run as on-premises virtual machines on VMware ESXi, Microsoft Hyper-V, or Linux KVM, as an on-premises hardware appliance, in VMware Cloud on AWS, or as an AMI in Amazon EC2. Volume Gateway can create incremental EBS snapshots and integrates with AWS Backup for managing backup and recovery of cached and stored volumes. Transfers between gateway appliances and AWS use SSL encryption. Stored data is encrypted by default with S3-SSE, with AWS KMS keys available as an option. Integrations include CloudWatch, CloudTrail, IAM, KMS, AWS Backup, S3, FSx for Windows File Server, EBS, and S3 Glacier storage tiers. The service supports hybrid deployment and usage-based billing.

Who it suits

AWS Storage Gateway suits organizations connecting on-premises applications to AWS storage while retaining local data caching. Its listed use cases include moving backups and archives to the cloud, cloud-backed on-premises file shares, low-latency access to AWS data, and data lake workflows.
