AWS Storage Gateway Interview Questions

1. What is AWS Storage Gateway?

Amazon Web Services (AWS) Storage Gateway is a hybrid cloud storage service that enables you to store data on-premises and in the cloud. It provides a connection between your on-premises data center and the cloud, allowing you to store data in Amazon Simple Storage Service (S3) or Amazon Elastic Block Store (EBS) while maintaining local access to your data.

There are three main types of Storage Gateway:

1. File Gateway: File Gateway is a file-based storage service that enables you to store and retrieve files in S3 using standard file protocols, such as Network File System (NFS) or Server Message Block (SMB).
2. Volume Gateway: Volume Gateway is a block-based storage service that enables you to store and retrieve data in S3 or EBS using standard iSCSI interfaces. It offers two options: Stored volumes, which store data locally and asynchronously upload it to S3, and Cached volumes, which store frequently accessed data locally and the rest in S3.
3. Tape Gateway: Tape Gateway is a tape-based storage service that enables you to store data on virtual tapes in S3 or on physical tapes in an AWS Storage Gateway Tape Library. It is designed for use with on-premises tape backup and archiving applications.

Storage Gateway is designed to be easy to set up and use and can be managed through the AWS Management Console or the AWS Storage Gateway API. It can help you reduce the costs and complexity of storing data both on-premises and in the cloud while providing the performance and reliability of local storage.
