Many applications listen to multiple event sources, update the state of correspondent business entities, and have to execute actions if some state is reached. Temporal is a good fit for many of these. It has direct support for asynchronous events (aka signals), has a simple programming model that obscures a lot of complexity around state persistence, and ensures external action execution through built-in retries.
