Single answerA company wants to integrate their on-premises infrastructure with AWS to provide low-latency access to frequently used files while securely storing the full dataset in Amazon S3. Which AWS service should they use?
- A
Amazon Elastic File System (EFS)
- B
AWS Storage Gateway - File Gateway
- C
Amazon FSx for Windows File Server
- D
AWS Direct Connect
Show answer and explanation
Correct answer: B
Explanation
AWS Storage Gateway - File Gateway is the correct service for this scenario because it allows on-premises applications to access files stored in Amazon S3 with low-latency performance through a local cache. This fulfills the company's need for low-latency access to frequently used files while securely storing the full dataset in the cloud.
- A. Incorrect.
Amazon Elastic File System (EFS) is a scalable file storage service designed for use with AWS services and on-premises resources. However, it is not specifically designed for caching frequently used files while storing the full dataset in Amazon S3.
- B. Correct.
AWS Storage Gateway - File Gateway enables on-premises applications to access Amazon S3 objects as files, providing a local cache for frequently accessed data and securely storing the full dataset in S3. This fits the requirements perfectly.
- C. Incorrect.
Amazon FSx for Windows File Server provides fully managed Windows file systems, but it is not intended for caching files locally with S3 as the backend storage.
- D. Incorrect.
AWS Direct Connect establishes a dedicated network connection between on-premises infrastructure and AWS, but it does not provide caching or file system integration with Amazon S3.
