A digital twin is the digital equivalent of a real-world system or product such as virtualized computers, analytical models and data, transactional data, visual models, computations, servers, storefronts, shopping carts, and more.
Other examples of digital twins include RPA as a tool to trigger processes and to detect quality issues. Offering an online checkout portal is a digital twin to a customer checking out with a sales representative using a cash register inside a physical store.
