AWS Storage Gateway
The AWS Storage Gateway’s software appliance is available for download as a virtual machine (VM) image that you install on a host in your datacenter. Once you’ve installed your gateway and associated it with your AWS Account through our activation process, you can use the AWS Management console to create either Gateway-Cached or Gateway-Stored storage volumes that can be mounted as iSCSI devices by your on-premises applications.
Amazon Simple Storage Service : Amazon S3 provides a highly durable, scalable, and secure storage infrastructure that is well-suited for backing up and archiving your critical data. The service redundantly stores data in multiple facilities and on multiple devices within each facility.
Amazon Glacier : Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable.
