This Guidance shows how you can build and run large-scale spatial simulations on AWS without having to manage the underlying compute, memory, or networking infrastructure. It uses AWS SimSpace Weaver, a fully managed service that lets you create complex and expansive simulation environments at scale. You specify the compute capacity needed for the simulation and define how it should be partitioned. While the spatial simulations are running, you can view the simulations in real-time, make modifications, or interact with the simulations to change the behavior of the dynamic entities and improve the representation of your unique scenarios.
