A company moved all media rendering data from on premises to Amazon S3 to reduce storage costs. The on-premises rendering application requires low-latency access to storage and must maintain its performance. Which storage solution meets these requirements MOST cost-effectively?

An Amazon S3 File Gateway provides a file interface to Amazon S3, allowing on-premises applications to access S3 objects as files using standard file protocols (NFS and SMB). It caches frequently accessed data locally, offering low-latency access while cost-effectively storing the bulk of the data in S3. Mountpoint for Amazon S3 allows direct S3 access but is primarily designed for data lakes and high-throughput workloads, not necessarily low-latency, file-system-like access for traditional applications. Copying data to Amazon FSx for Windows File Server would incur additional storage and data transfer costs, making it less cost-effective than S3 File Gateway. Configuring an on-premises file server and using the S3 API would require custom development and maintenance, increasing operational overhead and complexity, and might not provide the desired low-latency performance without significant local caching.
