A company needs on-premises workloads to access Windows file shares hosted in AWS but does not want to add any new infrastructure or applications in its data center. Which AWS service enables this?

Amazon FSx File Gateway allows on-premises applications to access file shares hosted on Amazon FSx for Windows File Server in AWS without requiring new on-premises infrastructure. It acts as a cache for frequently accessed data, providing low-latency access while transparently managing data transfer to and from AWS. AWS DataSync is used for high-speed, online data transfer between on-premises storage and AWS storage services, or between different AWS storage services, but it doesn't provide direct file share access for on-premises workloads. Amazon S3 is object storage and does not natively support Windows file shares. The AWS Snow Family is used for large-scale data migration and edge computing, not for enabling ongoing file share access.
