This document discusses using AWS for high performance computing to perform risk analysis simulations for financial services institutions. It outlines the challenges of limited on-premises capacity and inflexible hardware. AWS provides scalable compute resources, different instance types, storage options, and security tools. Example models for credit, market, and other risk are Compute-as-a-Service using EC2. Estimates show over 1 petaflop of capacity for under $0.025 per core hour using a mix of reserved and spot instances. AWS delivers flexible, secure infrastructure to meet financial risk management needs.
