Bridging the Gap: Hybrid Cloud Storage with AWS Storage Gateway

Many businesses are embracing the cloud, but the need for on-premises infrastructure often remains. Whether it’s for compliance, performance, or to support existing legacy systems, a hybrid approach is essential. AWS Storage Gateway offers a powerful solution, seamlessly connecting your on-premises data centers with the vast storage capabilities of the AWS cloud, including services like Amazon S3, Amazon EBS, and Amazon FSx.

Understanding the Need for Hybrid Cloud Storage

Hybrid cloud storage blends the best of both worlds: the control and low latency of on-premises storage with the scalability and cost-effectiveness of the cloud. This approach enables organizations to:

Expand On-Premises Storage: Easily extend your existing storage capacity to the cloud without impacting your current applications.
Enhance Disaster Recovery: Utilize cloud storage for robust backup and disaster recovery, while maintaining frequently accessed data locally for optimal performance.
Meet Compliance Needs: Store sensitive data on-premises to comply with regulations, while still leveraging the cloud for data processing and analytics.

What is AWS Storage Gateway?

AWS Storage Gateway is a service designed specifically for hybrid cloud environments. It allows on-premises applications to access AWS storage with minimal latency, while also providing seamless integration with a range of other AWS cloud services.

Key Advantages of AWS Storage Gateway

Effortless Cloud Integration: Seamlessly connect your on-premises workloads to the AWS cloud.
Optimized Data Transfer: Benefit from features like compression and caching to maximize performance and minimize bandwidth usage.
Reduced Storage Costs: Leverage the cost-effectiveness of AWS S3 and Glacier to reduce your on-premises storage expenses.
Security and Scalability: Enjoy robust security features like encryption and access controls, along with the ability to scale your storage automatically as needed.

Exploring the Different Types of AWS Storage Gateway

AWS Storage Gateway offers three distinct types, each tailored to address specific use cases:

A. File Gateway (NFS & SMB)

File Gateway presents a standard network file system interface (either NFS or SMB). It stores your files directly in Amazon S3, while intelligently caching frequently accessed data locally for rapid access. This is an excellent choice for:

File Sharing: Providing shared network access to files stored in the cloud.
Backup and Recovery: Backing up files to the cloud and restoring them quickly when needed.
Data Archiving:Storing files that needed, but with local access.

Example: A media production company needs scalable storage for its large video and image files. File Gateway allows them to store these files in Amazon S3, while providing their editors with fast, local access for editing and manipulation.

B. Volume Gateway (iSCSI)

Volume Gateway provides block storage using the industry-standard iSCSI protocol. It offers two distinct modes:

Cached Mode: Stores your most frequently accessed data locally, while keeping the complete data volumes in Amazon S3. This balances performance and cost-efficiency.
Stored Mode: Keeps a full copy of your data on-premises and asynchronously replicates it to AWS for backup and disaster recovery purposes.

Volume Gateway is ideal for scenarios such as:

Database Storage: Providing block storage for database applications.
Disaster Recovery: Ensuring business continuity by replicating data to the cloud.

Example: A financial institution running a critical database application on-premises requires a reliable cloud-based backup solution. Volume Gateway allows them to store the primary database data locally for optimal performance, while simultaneously backing up the volumes to AWS for disaster recovery.

C. Tape Gateway (VTL for Backup & Archival)

Tape Gateway offers a compelling alternative to traditional physical tape libraries. It presents itself as a virtual tape library (VTL) and stores virtual tapes in Amazon S3 Glacier, providing a cost-effective and highly durable solution for long-term data archiving. Tape Gateway is compatible with many popular backup applications, such as Veeam and NetBackup.

This is a perfect solution for:

Long-Term Archival: Storing data that needs to be retained for extended periods.
Compliance and Regulatory Requirements: Meeting industry-specific regulations that mandate data retention.

Example: A healthcare provider needs to retain patient medical records for many years to comply with regulations. Tape Gateway allows them to archive this data in Amazon S3 Glacier, significantly reducing their on-premises storage costs while ensuring long-term data preservation.

Architecting Hybrid Cloud Storage Solutions

AWS Storage Gateway supports various architectural patterns, including:

A. Active Data with S3 File Gateway

For applications that require high-speed access to frequently used datasets, while also benefiting from the durability of Amazon S3.

B. Disaster Recovery with Volume Gateway

Ensure business continuity by replicating your on-premises data volumes to AWS, providing a rapid recovery option in case of a disaster.

C. Archival Storage with Tape Gateway

Achieve cost-effective, long-term data retention and compliance with regulatory requirements using Tape Gateway and Amazon S3 Glacier.

Integrating with Other AWS Services

AWS Storage Gateway seamlessly integrates with a wide array of AWS services, enabling a comprehensive hybrid cloud storage strategy:

AWS Service	Integration Benefit
Amazon S3	Stores primary and backup data from File/Volume Gateway.
Amazon EBS	Provides iSCSI-based storage for databases via Volume Gateway.
AWS Backup	Automates backup scheduling for your hybrid storage solutions.
AWS S3 Glacier	Archives long-term data using Tape Gateway.
Amazon FSx	Offers Windows File Server integration for File Gateway.

Best Practices for Hybrid Cloud Storage with AWS

Leverage Caching: Minimize latency by storing frequently accessed data locally using the caching capabilities of Storage Gateway.
Implement Lifecycle Policies: Automatically move infrequently accessed data to S3 Glacier to reduce storage costs.
Prioritize Data Encryption: Protect your sensitive data using AWS Key Management Service (KMS) for encryption.
Monitor Performance: Utilize Amazon CloudWatch to gain insights into your storage performance and identify potential bottlenecks.
Optimize Large-Scale Data Transfers: Consider using AWS Direct Connect or AWS Snowball for efficient and secure transfer of large datasets.

Conclusion

AWS Storage Gateway empowers businesses to seamlessly bridge the gap between on-premises infrastructure and the cloud. By leveraging File, Volume, and Tape Gateway, organizations can achieve scalability, cost savings, enhanced disaster recovery, and efficient data management. This hybrid approach allows businesses to optimize their storage strategy based on their specific needs and requirements.
