AWS Storage Gateway

AWS Storage Gateway is a hybrid cloud storage service that provides on-premises access to virtually unlimited cloud storage. It seamlessly connects on-premises environments with AWS cloud storage, enabling you to store data securely and efficiently in AWS while maintaining low-latency access from on-premises applications.

Key Features

• Hybrid Cloud Storage: AWS Storage Gateway offers seamless integration between on-premises environments and AWS, enabling hybrid cloud storage solutions.
• Multiple Gateway Types: Supports various gateway types, including File Gateway, Volume Gateway, and Tape Gateway, to suit different storage needs.
• Data Encryption: All data transferred between your on-premises environment and AWS is encrypted using SSL, and data stored in AWS is encrypted at rest using AWS KMS.
• Low-Latency Access: Provides low-latency access to frequently accessed data, ensuring fast performance for on-premises applications.
• Cost-Effective Storage: Enables cost-effective storage by leveraging AWS cloud storage, reducing the need for on-premises storage infrastructure.

Architecture Overview

The following diagram illustrates how AWS Storage Gateway integrates your on-premises storage with AWS cloud storage:

• On-Premises Applications: On-premises applications interact with AWS Storage Gateway as if it were a local storage device, providing seamless access to AWS cloud storage.
• Storage Gateway Appliance: The Storage Gateway appliance runs on-premises and acts as a bridge between your local environment and AWS cloud storage.
• AWS Cloud Storage: Data stored on the Storage Gateway is backed by Amazon S3, Amazon EBS, or Amazon Glacier, depending on the gateway type.
• Data Transfer and Caching: Frequently accessed data is cached locally on the gateway appliance, while less frequently accessed data is stored in the cloud, optimizing performance and cost.

Use Cases

• Data Backup and Archiving: Use AWS Storage Gateway for efficient, secure backup and archiving of on-premises data to AWS cloud storage.
• Disaster Recovery: Enable disaster recovery by replicating critical data to AWS, ensuring data availability in the event of an on-premises failure.
• Hybrid Cloud Architectures: Integrate on-premises applications with AWS storage services, enabling a hybrid cloud storage solution.
• Tape Replacement: Replace physical tape libraries with Tape Gateway, leveraging the scalability and durability of Amazon S3 and Amazon Glacier.

Integration with Other AWS Services

AWS Storage Gateway integrates with various AWS services to provide a comprehensive storage solution:

• Amazon S3: Store data in Amazon S3 using File Gateway for scalable, secure, and durable cloud storage.
• Amazon Glacier: Archive data to Amazon Glacier using Tape Gateway for cost-effective, long-term storage.
• Amazon EBS: Use Volume Gateway to create EBS snapshots, enabling efficient backups and disaster recovery.
• AWS CloudTrail: Monitor and log all API calls made by AWS Storage Gateway, ensuring compliance and security.
