Key Features

  • Hybrid Architecture: Integrates on-premises environments with AWS, enabling seamless data access.
  • Scalability: Easily scale storage resources based on changing data requirements.
  • Cost Efficiency: Reduces storage costs by leveraging AWS pricing models.
  • Data Security: Ensures secure data transfer and storage through encryption and access control.

Use Cases

  • Backup and Disaster Recovery: Provide backup solutions and disaster recovery options by archiving data to the cloud.
  • Data Migration: Facilitate the migration of data to AWS for cost savings and improved accessibility.
  • Cloud Bursting: Allow businesses to handle peak loads by offloading storage to the cloud.

AWS Storage Gateway Architecture

Components of Storage Gateway

AWS Storage Gateway consists of several components:

  • Gateway Appliance: A virtual appliance that runs on-premises and connects to AWS services.
  • Cloud Storage: AWS services such as Amazon S3, Amazon EBS, and AWS Backup where data is stored.
  • On Premises Applications: Applications that access storage through the Storage Gateway.

Gateway Types

File Gateway

File Gateway allows you to use Amazon S3 as a file system. It exposes a file share interface using standard file protocols like NFS and SMB, enabling on-premises applications to store and retrieve files directly in Amazon S3.

Volume Gateway

Volume Gateway offers two configurations: stored volumes and cached volumes. Stored volumes keep the entire dataset on-premises, while cached volumes store frequently accessed data locally, with the remainder in Amazon S3.

Tape Gateway

Tape Gateway provides a virtual tape interface, allowing you to backup data to the cloud using existing backup applications. It emulates a physical tape library, providing a seamless transition from on-premises tape systems to AWS.

 Data Flow

The data flow in AWS Storage Gateway can be summarized as follows:

  1. Data Access: On-premises applications access the Storage Gateway through file, block, or tape protocols.
  2. Data Processing: The Gateway processes the requests and interacts with AWS storage services.
  3. Storage: Data is stored in Amazon S3 or other AWS storage services based on the configured gateway type.
