Event-based systems

Event-based systems are software architectures that respond to specific events or changes in state, such as user actions or updates from other services. Instead of constantly checking for changes, these systems listen for events and react accordingly. For example, when you receive a notification on your phone, it’s likely because an event occurred, like someone sending you a message. This approach allows for more efficient processing, as resources are only used when needed, making it ideal for applications such as online gaming, real-time data processing, and responsive user interfaces.
