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).
Test yourself
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?
- Amazon EFS
- Amazon FSx for Lustre
- Amazon FSx for Windows File Server
- 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.
