The AWS Storage Gateway is a service connecting an on-premises software appliance with cloud-based storage to provide seamless and secure integration between an organization's on-premises IT environment and AWS's storage infrastructure.
- Provides low-latency performance by maintaining frequently accessed data on-premises while securely storing all of your data encrypted in Amazon Simple Storage Service (Amazon S3) or Amazon Glacier.
AWS Storage Gateway supports three configurations
- Gateway-Cached Volumes: Gateway-Cached Volumes provide substantial cost savings on primary storage, minimize the need to scale your storage on-premises, and provide low-latency access to your frequently accessed data.
- Gateway-Stored Volumes: In the event you need low-latency access to your entire data set, you can configure your gateway to store your primary data locally, and asynchronously back up point-in-time snapshots of this data to Amazon S3.
