This lab simulates and event-based application. An event-based application is a software architecture pattern where components of the system communicate through events. Events are discrete messages that represent a change in state or occurrence in the system. In event-driven-architecture, components are decoupled, which allows them to act independently when an event is generated, leading to improved scalability, flexibility, and fault tolerance.
