A company is running a data-intensive application on AWS. The application runs on a cluster of hundreds of Amazon EC2 instances. A shared file system also runs on several EC2 instances that store 200 TB of data. The application reads and modifies the data on the shared file system and generates a report. The job runs once monthly, reads a subset of the files from the shared file system, and takes about 72 hours to complete. The compute instances scale in an Auto Scaling group, but the instances that host the shared file system run continuously. The compute and storage instances are all in the same AWS Region. A solutions architect needs to reduce costs by replacing the shared file system instances. The file system must provide high performance access to the needed data for the duration of the 72-hour run. Which solution will provide the LARGEST overall cost reduction while meeting these requirements?

Chose A1
Option A delivers: Massive cost savings (thanks to S3 Intelligent-Tiering and ephemeral FSx). High Performance for compute-intensive workloads. Scalability and simplicity using managed AWS services.
I lean more towards D but I am not sure whether the Gateway is only intended for on-premise as few are mentioning here. If that is not the case then the right option is D.
