Exploring event-based architecture

Event-based systems revolve around processing events, which are defined as changes in the state of a system. There are components that generate events, the channels through which the events propagate, and the listeners who react to them, potentially triggering new events too. It's a style that promotes asynchrony and loose coupling, which increases performance, scalability, and ease of deployment.With those advantages, there are also some challenges to solve. One of them is the complexity to create a system of this type. All the queues must be made fault-tolerant so that no events are lost in the middle of being processed. Processing transactions in a distributed way is also a challenge on its own. Using the Correlation ID, a unique identifier attached to requests or messages, to track events between processes, along with monitoring techniques, can save you hours of debugging and scratching your head.Examples of event-based systems include stream...
