Question #: 43
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A solutions architect is designing storage for a high performance computing (HPC) environment based on Amazon Linux. The workload stores and processes a large amount of engineering drawings that require shared storage and heavy computing.
Which storage option would be the optimal solution?

A. Amazon Elastic File System (Amazon EFS)
B. Amazon FSx for Lustre
C. Amazon EC2 instance store
D. Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io1)

Show Suggested Answer

Suggested Answer: B 🗳️
Explanation -

Amazon FSx for Lustre -
Amazon FSx for Lustre is a new, fully managed service provided by AWS based on the Lustre file system. Amazon FSx for Lustre provides a high-performance file system optimized for fast processing of workloads such as machine learning, high performance computing (HPC), video processing, financial modeling, and electronic design automation (EDA).
FSx for Lustre allows customers to create a Lustre filesystem on demand and associate it to an Amazon S3 bucket. As part of the filesystem creation, Lustre reads the objects in the buckets and adds that to the file system metadata. Any Lustre client in your VPC is then able to access the data, which gets cached on the high- speed Lustre filesystem. This is ideal for HPC workloads, because you can get the speed of an optimized Lustre file system without having to manage the complexity of deploying, optimizing, and managing the Lustre cluster.
Additionally, having the filesystem work natively with Amazon S3 means you can shut down the Lustre filesystem when you don't need it but still access objects in
Amazon S3 via other AWS Services. FSx for Lustre also allows you to also write the output of your HPC job back to Amazon S3.

Agree it’s option B Lustre actually stands for Linux and cluster - hence it’s perfect HPC

Though B goes with HPC. I still dont get why EFS or EBS-io1 wont work? Both can work for Linux instances and be shared across multiple EC2?(EBS has multi attach for io1/2)?
