AWS Storage Gateway

Amazon 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. This service enables customers to store data locally for low-latency access and backup to the AWS cloud for disaster recovery and long-term retention.

There are three types of storage gateways:

  • File Gateway: allows you to store and retrieve files as objects in Amazon S3 and access them using the industry-standard SMB and NFS protocols.
  • Volume Gateway: provides two storage options: stored volumes and cached volumes. Stored volumes allow you to store your primary data locally, while asynchronously backing up that data to S3. Cached volumes store your primary data in S3 and keep frequently accessed data locally.
  • Tape Gateway (VTL): emulates a virtual tape library and enables you to store large amounts of data on virtual tapes that are stored in S3 or Glacier.

Storage Gateway offers several benefits:

  • Data is stored on-premises and in the cloud, providing a hybrid storage solution.
  • Data stored on-premises can be backed up to the cloud for disaster recovery and long-term retention.
  • Data stored in the cloud can be accessed from on-premises using industry-standard protocols.
  • Data stored in the cloud can be easily integrated with other AWS services, such as Amazon Elastic Compute Cloud (EC2) and Amazon Elastic Block Store (EBS).
  • Cost-effective, as you only pay for the storage and data transfer you use.

Storage Gateway can be used in a variety of scenarios, including disaster recovery, archiving, and data migration. It is a cost-effective and secure way to integrate on-premises storage with the cloud and gain the benefits of both worlds.
