Which solution meets these requirements?
Create an Amazon Elastic File System (Amazon EFS) file system. Mount the file system on each of the EC2 instance.
Create an Amazon S3 bucket. Mount the S3 bucket on each of the EC2 instances.
Ensure that the EC2 instances are Amazon Elastic Block Store (Amazon EBS) optimized. Mount Provisioned IOPS SSD (io2) EBS volumes with Multi-Attach on each instance.
Create an Amazon FSx for Lustre file system. Mount the file system on each of the EC2 instances.
Explanations:
Amazon EFS is suitable for general file storage but does not meet the high throughput, low latency, and millions of IOPS requirements for high-performance computing.
Amazon S3 is an object storage service, not designed for sub-millisecond latencies or high throughput. It cannot be mounted directly on EC2 instances like a file system.
Amazon EBS (io2) volumes provide high performance but do not meet the shared storage requirement across multiple instances for HPC workloads. Multi-Attach is limited.
Amazon FSx for Lustre is a high-performance file system that meets sub-millisecond latencies, high throughput, and millions of IOPS. It is designed for HPC workloads.
From what I’ve seen, the answer is:
Create an Amazon FSx for Lustre file system. Mount the file system on each of the EC2 instances.
