SAA-C03 Question 416
Single answerA large enterprise wants to migrate its on-premises file storage to AWS while maintaining low-latency access for its on-premises applications. The company also needs a solution to periodically archive cold data to Amazon S3 for cost-effectiveness. Which hybrid storage solution would best meet these requirements?
- A
AWS DataSync
- B
AWS Transfer Family
- C
AWS Storage Gateway - File Gateway
- D
Amazon S3 Glacier
Show answer and explanation
Correct answer: C
Explanation
AWS Storage Gateway - File Gateway is the ideal solution for this scenario because it allows on-premises applications to access files stored in Amazon S3 using standard file protocols, while providing low-latency performance. Additionally, it seamlessly integrates with Amazon S3 for storing and archiving data, meeting the company's requirements for cost-effective archival storage.
- A. Incorrect.
AWS DataSync is primarily used for one-time or recurring high-speed transfers of data between on-premises and AWS storage, but it does not provide low-latency access for on-premises applications.
- B. Incorrect.
AWS Transfer Family supports transferring files into and out of Amazon S3 using protocols like SFTP, FTPS, and FTP, but it is not designed for hybrid storage or low-latency access.
- C. Correct.
AWS Storage Gateway - File Gateway is specifically designed for hybrid storage use cases. It enables on-premises applications to access files in Amazon S3 with low latency while also allowing seamless archiving of cold data to S3.
- D. Incorrect.
Amazon S3 Glacier is designed for long-term storage of archival data at low cost but does not address the need for hybrid storage or low-latency access.
