This intermediary, the event bus, receives messages or events from publishers and routes them to subscribers that have registered interest in those specific events.
The primary benefit of the tapahtumavälittäjä pattern is decoupling. Publishers do not need to know about the
Event buses are commonly used in microservices architectures, asynchronous processing, and distributed systems. They allow for
