Final answer:
The most suitable service for this scenario is Amazon FSx for Lustre, which is a scalable, high-performance file system optimized for HPC workloads. It works natively with Amazon S3 and provides a high-performance POSIX interface for efficient data processing.
Step-by-step explanation:
The most suitable service for the described scenario would be Amazon FSx for Lustre. It is a fully managed file system optimized for high-performance computing workloads. Amazon FSx for Lustre is designed to deliver parallel file systems for HPC applications, providing scalable storage with high throughput and low latency.
It works natively with Amazon S3, allowing you to access and process data stored in S3 with a high-performance POSIX interface. This enables you to efficiently utilize S3 data within your HPC cluster. Amazon FSx for Lustre is a scalable solution that can easily handle the requirements of a high-performance file system for the HPC cluster.
Amazon Elastic File System (EFS) is not the most suitable option as it is a shared file system and may not provide the necessary performance for an HPC cluster. Amazon Elastic Block Storage (EBS) is block-level storage and not optimized for parallel processing, which makes it less suitable for HPC workloads. Amazon FSx for Windows File Server is designed for Windows-based workloads, making it less ideal for the described scenario.
