A company wants to use high performance computing (HPC) infrastructure on AWS for financial risk modeling. The company's HPC workloads run on Linux. Each HPC workflow runs on hundreds of Amazon EC2 Spot Instances, is short-lived, and generates thousands of output files that are ultimately stored in persistent storage for analytics and long-term future use.
The company seeks a cloud storage solution that permits the copying of on-premises data to long-term persistent storage to make data available for processing by all EC2 instances. The solution should also be a high performance file system that is integrated with persistent storage to read and write datasets and output files.
Which combination of AWS services meets these requirements?

A
Amazon FSx for Lustre integrated with Amazon S3
B
Amazon FSx for Windows File Server integrated with Amazon S3
C
Amazon S3 Glacier integrated with Amazon Elastic Block Store (Amazon EBS)
D
Amazon S3 bucket with a VPC endpoint integrated with an Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2) volume
Explanation:
Explanation
Amazon FSx for Lustre integrated with Amazon S3 is the correct solution because:
-
High Performance Computing (HPC) Requirements: FSx for Lustre is specifically designed for HPC workloads and provides high-performance parallel file system capabilities that are ideal for Linux-based HPC applications.
-
Integration with Persistent Storage: FSx for Lustre can be seamlessly integrated with Amazon S3, allowing:
- Data to be copied from on-premises to S3 for long-term persistent storage
- S3 data to be automatically loaded into the Lustre file system for high-performance processing
- Output files to be written back to S3 for analytics and long-term storage
-
Linux Compatibility: FSx for Lustre is fully compatible with Linux workloads, which matches the company's requirement.
-
Spot Instance Support: The solution works well with EC2 Spot Instances, which are commonly used for cost-effective HPC workloads.
Why other options are incorrect:
- Option B: Amazon FSx for Windows File Server is designed for Windows workloads, not Linux-based HPC applications.
- Option C: S3 Glacier is for archival storage with retrieval delays, not suitable for high-performance file system access. EBS volumes are not integrated with on-premises data copying.
- Option D: While S3 with VPC endpoints provides access, it doesn't offer the high-performance parallel file system capabilities needed for HPC workloads. EBS gp2 volumes are block storage, not a high-performance file system.
Key Benefits:
- FSx for Lustre provides sub-millisecond latencies for HPC workloads
- Automatic data tiering between S3 and Lustre file system
- Scales to thousands of EC2 instances
- Cost-effective with Spot Instances
- Persistent storage in S3 for analytics and long-term use
