Answer: Use Amazon FSx for Lustre persistent file systems.
## Explanation **Correct Answer: B - Use Amazon FSx for Lustre persistent file systems.** **Why this is the correct choice:** 1. **High Performance Computing (HPC) Requirements**: The scenario describes a weather forecasting company with HPC needs that requires: - Processing hundreds of gigabytes of data - Sub-millisecond latency - Large amounts of sustained throughput - Accessible to thousands of compute instances simultaneously 2. **Amazon FSx for Lustre**: This is specifically designed for HPC workloads: - **Lustre** is a parallel file system designed for high-performance computing - Provides sub-millisecond latencies - Supports thousands of compute instances accessing data simultaneously - Delivers high throughput (up to hundreds of GB/s) - Scales to petabytes of data 3. **Persistent vs Scratch File Systems**: - **Persistent file systems (Option B)**: Provide durable storage that persists independently of compute instances, which is appropriate for a production forecasting system - **Scratch file systems (Option A)**: Are temporary storage optimized for short-lived, high-performance workloads and data is not persisted long-term 4. **Why not Amazon EFS (Options C & D)**: - Amazon EFS is designed for general-purpose file storage - While EFS can scale, it's not optimized for HPC workloads requiring sub-millisecond latency - EFS uses NFS protocol which has higher latency compared to Lustre - EFS is better suited for web serving, content management, and shared file storage rather than HPC 5. **Key Requirements Met**: - **Sub-millisecond latency**: FSx for Lustre delivers this - **Sustained throughput**: FSx for Lustre provides consistent high throughput - **Thousands of compute instances**: Lustre's parallel architecture supports massive concurrent access - **Highly available**: FSx for Lustre persistent file systems are highly available across multiple Availability Zones **Additional Context**: - FSx for Lustre integrates well with AWS compute services like EC2, Batch, and ParallelCluster - It can be connected to S3 for data tiering and cost optimization - The persistent option ensures data durability and availability for ongoing forecasting operations

A weather forecasting company needs to process hundreds of gigabytes of data with sub-millisecond latency. The company has a high performance computing (HPC) environment in its data center and wants to expand its forecasting capabilities.
A solutions architect must identify a highly available cloud storage solution that can handle large amounts of sustained throughput. Files that are stored in the solution should be accessible to thousands of compute instances that will simultaneously access and process the entire dataset.
What should the solutions architect do to meet these requirements?
A
Use Amazon FSx for Lustre scratch file systems.
B
Use Amazon FSx for Lustre persistent file systems.
C
Use Amazon Elastic File System (Amazon EFS) with Bursting Throughput mode.
D
Use Amazon Elastic File System (Amazon EFS) with Provisioned Throughput mode.
