Which storage option should the solutions architect recommend?
Create an Amazon S3 bucket for the application and establish an IAM role for Fargate to communicate with Amazon S3.
Create an Amazon FSx for Lustre file share and establish an IAM role that allows Fargate to communicate with FSx for Lustre.
Create an Amazon Elastic File System (Amazon EFS) file share and establish an IAM role that allows Fargate to communicate with Amazon Elastic File System (Amazon EFS).
Create an Amazon Elastic Block Store (Amazon EBS) volume for the application and establish an IAM role that allows Fargate to communicate with Amazon Elastic Block Store (Amazon EBS).
Explanations:
Amazon S3 is an object storage service, not a file system, and does not support concurrent access to files in the way that a file system like EFS or FSx for Lustre can. It also does not provide the high performance required for machine learning workloads.
Amazon FSx for Lustre provides high performance for workloads like machine learning, but it is typically used with EC2 instances, not AWS Fargate. Fargate does not natively support FSx for Lustre as a mount option.
Amazon EFS is a scalable file system that supports concurrent file access and can be mounted by AWS Fargate tasks. It provides the shared storage needed for machine learning workloads and can deliver the high performance required.
Amazon EBS is block storage, which is suitable for persistent data storage but is not designed for shared concurrent access across multiple Fargate tasks. It is better suited for individual EC2 instances rather than containerized applications on Fargate.
I rate that the answer is:
Create an Amazon Elastic File System (Amazon EFS) file share and establish an IAM role that allows Fargate to communicate with Amazon Elastic File System (Amazon EFS).
