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.
