Understanding hybrid storage options is crucial when preparing for the AWS Certified Solutions Architect – Associate (SAA-C03) exam. Specifically, DataSync, Transfer Family, and Storage Gateway, which allow you to effectively manage, transfer, and integrate data across on-premises and cloud environments.
Let’s delve into each of these options, their features, and their potential use-cases.
1. AWS DataSync
AWS DataSync is an online data transfer service that simplifies, accelerizes, and automates moving data between on-premises storage systems and AWS storage services, or between AWS storage services.
Key Features:
- Simplified, fast transfer: Uses a purpose-built protocol and parallel transfers to achieve high speeds. Moreover, it’s simple to set up and manage.
- Data Protection: It verifies data integrity at each step to ensure that your data is safely transferred.
- Flexibility: Supports data transfers between various combinations of on-premises and AWS storage.
Use case: Suppose you have an application that generates large amounts of data regularly. Using DataSync, you can configure automated data transfers at regular intervals to move this data to AWS for processing or storage.
2. AWS Transfer Family
The AWS Transfer Family is a fully managed service that enables the transfer of files over the internet or direct connect link into and out of AWS storage services using SFTP, FTPS, and FTP.
Key Features:
- Seamless migration: Supports existing FTP, SFTP, and FTPS clients which allows for easy migration with minimal changes.

Use case:If you’re running a data processing pipeline that involves regular file transfers from third-party systems, you can use the AWS Transfer Family for secure, scalable, and managed transfers.
3. AWS Storage Gateway
AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. It combines a multi-protocol storage appliance with highly efficient network connectivity, providing seamless integration with data security features to bring Amazon S3, Amazon EFS, and Amazon FSx for Windows File Server to virtually any on-premises environment.
Key Features:
- Integration: Smooth integration with existing applications while leveraging on-demand cloud storage.
- Several types of gateways: File Gateway, Volume Gateway, and Tape Gateway.
- Caching: Frequently accessed data can be cached for low-latency access.
Use case: If you have a local application that needs low-latency access to large datasets. You can use the File Gateway type within the AWS Storage Gateway service to store and retrieve objects in Amazon S3 with maximum efficiency.
Conclusion
Understanding these hybrid storage options and their use-cases give you the versatility to design and implement robust, flexible, and cost-effective solutions on AWS. For the SAA-C03 exam, you should get familiar with when and where to implement these services effectively. Make sure you delve deeper into each service’s specifics, going beyond the overview provided here, to ensure you’re well-prepared for any related questions in the exam.
