Using powerful cloud computers to create virtual models of real-world systems and test how they behave under different conditions. Like building a digital twin of a bridge to test how it handles hurricanes before constructing the real thing — cloud simulation provides the massive computing power needed to run complex calculations that would take years on a regular computer.
An automotive company uses AWS High Performance Computing (HPC) clusters with hundreds of GPUs to simulate thousands of crash test scenarios for a new car design in days instead of months, saving millions in physical prototype costs while testing far more safety configurations than would be possible with real crash tests.
These services help you run large-scale simulation workloads by provisioning and managing HPC-style compute clusters (often with GPUs), scheduling jobs, and scaling resources up/down for batch simulations.
