- [Instructor] Event-driven architecture is an architecture style that uses event and asynchronous communication to loosely couple an application component. Event-driven architectures can help you to boost agility and build reliable, scalable applications. Before getting started with event-driven applications, it is important to understand the difference between tight versus loose coupling. Coupling is the measure of dependency each component of an application has on one another. For example, a component needs to call another in order to complete a task, and the order in which things are called matter. Tightly coupled systems can be particular effective if the application has few components or if a single team or developer owns the entire application. However, when components are more tightly coupled, it becomes increasingly likely that a change or an operational issue in one component will propagate to others. For…
