Getting On The Cloud: 12 Cloud Storage Gateways
Joseph F. Kovar
Amazon Web Services (AWS) Storage Gateway
The AWS Storage Gateway service provides a seamless and secure connection of on-premise software appliances with AWS' cloud-based storage. It supports industry-standard storage protocols, and maintains frequently accessed data on-premise while storing all data encrypted in Amazon S3 or Amazon Glacier. The AWS Storage Gateway supports three configurations, including a gateway-cached volume with primary data in Amazon S3 and hot data in local storage; a gateway-stored volume combining local primary storage with asynchronous backups to Amazon S3, and a gateway virtual tape library that uses the standard iSCSI interface to back data up to virtual tapes backed by Amazon S3 or Amazon Glacier.
