A financial services firm is migrating its high performance computing (HPC) workloads to AWS for advanced risk modeling. These workloads are Linux-based, run on hundreds of EC2 Spot Instances, and generate large volumes of output files that must be retained for long-term analytics. The company also wants to copy some datasets from its on-premises storage into the cloud and make the data accessible to all compute nodes during processing. The cloud storage solution must deliver high-throughput, low-latency performance, and must be able to integrate with persistent storage for final data archiving. What AWS solution best meets these requirements?
