service that enables hybrid storage between on-premises environments and AWS; integrates on-premise applications and workflows with cloud storage
How are files stored?

What are the different storage solutions?
file gateways, volume cached & storage gateways and tape gateways
What is a file gateway?

What is a stored volume, volume gateway?
low-latency, asynchronous storage to S3. PIT snapshot backups, 1 GB to 16 TB per volume with support of up to 32 volumes
What is a tape gateway?
virtual tape library interface for virtual tape drives for iSCL storage volumes. Integrated with Glacier.
