Introduction
Event-driven architecture is becoming a central part of distributed systems. However, determining when to use events or event APIs can be challenging. This guide provides clarity on these concepts.
What Are Events?
Events are occurrences or changes in the system state. They encapsulate information about these changes and are typically communicated asynchronously.
What Are Event APIs?
Event APIs are interfaces that enable applications to publish, consume, and react to events. They are structured ways to facilitate event-driven communication.
When to Use Events?
Events are ideal for notifying multiple components about state changes. They are useful when you need asynchronous communication and loose coupling between services.
When to Use Event APIs?
Event APIs are beneficial when there is a need for more structured interaction and control over event consumption. They also provide mechanisms to manage event flows effectively.
Comparison and Integration
Events and event APIs are not mutually exclusive and can often complement each other. Using both can provide a robust framework for event-driven systems.
Conclusion
Understanding the distinction between events and event APIs is crucial for designing effective distributed systems. Both have their unique advantages and, when used together, offer a comprehensive solution to handling events.
