FSx for Lustre is a high-performance file system built for compute-intensive workloads — machine learning, HPC, media processing — that need to process data in S3 at massive speed.

When it fits

The tell is high-performance computing or ML training that needs a fast, parallel file system, often integrated with S3 (it can present S3 data as a file system and write results back). Distinguish from FSx for Windows (SMB file shares) and EFS (general Linux NFS).

Practice question

A machine-learning training job needs a high-performance, parallel file system to process large datasets stored in S3 at very high throughput. Which service?

  1. Amazon EFS
  2. Amazon FSx for Lustre
  3. Amazon FSx for Windows File Server
  4. Amazon S3 alone
👉 Click to reveal the answer & explanation

Correct answer: B. FSx for Lustre is a high-performance parallel file system integrated with S3, built for HPC and ML. EFS (A) is general-purpose NFS with lower throughput; FSx for Windows (C) is SMB for Windows; S3 alone (D) isn’t a low-latency parallel file system.
