Question

A media company runs an on-premises application that reads and writes large files using standard NFS mounts. The team wants to reduce their on-premises storage footprint by keeping the primary copy of data in Amazon S3 while still giving the application low-latency access to frequently used files. They also want to avoid rewriting the application to use S3 APIs. Which solution best meets these requirements?

Accepted Answer

Deploy AWS Storage Gateway in File Gateway mode, which presents an NFS interface backed by S3 and caches frequently accessed data locally.

Answer

Use AWS DataSync to copy files to S3 on a schedule, and have the application read directly from the S3 bucket.

Answer

Deploy AWS Storage Gateway in Volume Gateway (stored volumes) mode to keep full data copies on-premises and back up to S3.

Answer

Mount an Amazon EFS file system over AWS Direct Connect so the application continues using NFS while data resides in AWS.
