AWS > Storage > Storage Gateway:
AWS Storage Gateway is a service that connects 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.
The service enables you to securely store data to the AWS cloud for scalable and cost-effective storage.
AWS Storage Gateways's software appliance is available for download as a virtual machine(VM) image that install on a host in your datacenter.
Storage Gateway support either VMware ESXi or Microsoft Hyper-V.
Once you've installed your gateway and associated it with your AWS account through the activation process, you can use the AWS Management Console to create the storage gateway option that is right for you.
Four Types of Storage Gateways
1. File Gateway(NFS):
Files are stored as objects in your S3 buckets, accessed through a Network File System(NFS) mount point.
2. Volume Gateway
The volume interface presents your applications with disk volumes using the iSCSI block protocol.
2A. Volume Gateway - Stored Volumes
Stored volumes let you store your primary date locally, while asynchronously backing up that date to AWS.
2B. Volume Gateway - Cached Volumes
Cached volumes let you use Amazon S3 as your primary data storage while retaining frequently accessed data locally in your storage gateway.
3. Tape Gateway
The VTL interface it provides let you leverage your existing tape-based backup application infrastructure to store data on virtual tape cartridges that you create on your tape gateway.
