Publish domain events to trigger downstream commands and create a reactive chain of collaboration across multiple components.

Each component leverages value-added cloud services to implement one or more cloud-native databases that are exclusively owned by each component. Data from upstream components is synchronized to these cloud-native databases to provide...
