Amazon Storage Gateway is a hybrid cloud storage service that connects your existing on-premises environments with the Amazon Web Services Cloud. Its features make it easy for you to run hybrid cloud workloads at any stage of your cloud adoption, whether it's getting started with cloud backups, accessing file shares, running cloud processing workflows for data generated by on-premises machines, or performing a one-time migration of block volume data or databases.

Key Product Features

Standard Storage Protocols

Storage Gateway seamlessly connects to your local production or backup applications with NFS, SMB, iSCSI, or iSCSI-VTL, so you can adopt Amazon Web Services Cloud storage without needing to modify your applications. Its protocol conversion and device emulation enables you to access block data on volumes managed by Storage Gateway on top of Amazon S3, store files as native Amazon S3 objects or fully managed file shares in Amazon FSx; keep virtual tape backups online in a Virtual Tape Library backed by S3 or move the backups to a tape archive tier on Amazon S3 Glacier.

Fully Managed Cache

The local gateway appliance maintains a cache of recently written or read data so your applications can have low-latency access to data that is stored durably in Amazon Web Services. The gateways use a read-through and write-back cache.

Optimized and Secured Data Transfer

Storage Gateway provides secure upload of changed data and secure downloads of requested data, encrypting data in transit between any type of gateway appliance and Amazon Web Services using SSL. Optimizations such as multi-part management, automatic buffering, and delta transfers are used across all gateway types, and data compression is applied for all block and virtual tape data.

Amazon Web Services Integrated

As a native Amazon Web Services service, Storage Gateway integrates with other Amazon Web Services services for storage, backup, and management. The service stores files as native Amazon S3 objects or native Amazon FSx files, archives virtual tapes in Amazon S3 Glacier, and stores EBS Snapshots generated by the Volume Gateway with Amazon EBS. Storage Gateway also integrates with Amazon Backup to manage backup and recovery of Volume Gateway volumes, simplifying your backup management, and helps you meet your business and regulatory backup compliance requirements. Storage Gateway publishes health and performance logs and metrics to Amazon CloudWatch and provides monitoring of metrics and alarms in the Storage Gateway console. File Gateway also publishes audit logs for SMB file share user operations to CloudWatch.

High Availability on VMware

Storage Gateway provides high availability on VMware through a set of health-checks integrated with VMware vSphere High Availability (VMware HA). With this integration, a Storage Gateway deployed in a VMware environment on-premises will automatically recover from most service interruptions in under 60 seconds. This protects storage workloads against hardware, hypervisor, or network failures, storage errors, or software errors, such as connection timeouts and file share or volume unavailability.

Additionally, Storage Gateway provides a consistent management experience using the Amazon Web Services Console, both for on-premises gateways, and for monitoring, management, and security with Amazon Web Services services such as Amazon CloudWatch, Amazon CloudTrail, Amazon Identity and Access Management (IAM), and Amazon Key Management Service (KMS).
