A medical research lab produces study data that must be available with minimal latency to clinics across the country for their on-premises, file-based applications. The data files are stored in an Amazon S3 bucket and clinics have read-only access. What should a solutions architect recommend?

Deploying an AWS Storage Gateway File Gateway as a virtual machine (VM) on-premises at each clinic is the best solution. File Gateway provides a local cache for frequently accessed S3 data, offering low-latency access for file-based applications while keeping the authoritative data in S3. This meets the requirement for minimal latency and read-only access. Migrating files with AWS DataSync is incorrect because it's a one-time or scheduled transfer service, not a real-time, low-latency access solution for ongoing file-based applications. Deploying a Volume Gateway is incorrect because it provides block storage (iSCSI) to on-premises applications, not file-based access, and is typically used for backups or disaster recovery, not direct file access from S3. Attaching Amazon EFS to on-premises servers is incorrect because EFS is a cloud-native NFS file system. While it can be accessed from on-premises via AWS Direct Connect or VPN, it doesn't provide the local caching benefits of a File Gateway for minimal latency access to S3 data.
