SAA-C03 Q182 · Storage

Question

A company wants to run a hybrid workload for data processing. The data needs to be accessed by on-premises applications for local data processing using an NFS protocol, and must also be accessible from the AWS Cloud for further analytics and batch processing. Which solution will meet these requirements?

Accepted Answer

**Answer A: AWS Storage Gateway File Gateway** satisfies every requirement:

1. **NFS protocol support**: File Gateway natively exposes an **NFS (and SMB) mount point** to on-premises applications. This directly meets the requirement for local data processing via NFS.

2. **On-premises local data processing**: On-premises applications mount the file gateway as a standard NFS share and read/write files normally, enabling local data processing with no application changes.

3. **Data accessible from AWS Cloud**: Behind the scenes, File Gateway stores files as **objects in Amazon S3**. Each file on the NFS share maps to an S3 object. This means AWS-native services like Amazon Athena, Amazon EMR, AWS Glue, or AWS Lambda can directly access the data in S3 for analytics and batch processing.
