Building Lightning-Fast, Scalable Systems with Event-Driven Design
Intro
Event-driven systems in IT refer to the design and implementation of software systems that are built around the notion of “events.” In an event-driven system, events are the primary means of communication between different components of the system.
Event
An event is a notification or trigger that something has happened, such as a user interaction with a web application, the completion of a background task, or a change in data. In an event-driven system, these events are captured and used to trigger specific actions or responses within the system.
Actors
In event-driven systems, the components that produce events are called producers, and the components that consume events are called consumers. Producers publish events, which are then received and processed by consumers. This allows for a loosely coupled and highly scalable architecture, as producers and consumers can be developed and deployed independently.
The benefits of event-driven systems include:
Scalability
One of the main benefits of event-driven systems is their scalability. Because events can be distributed and processed by multiple consumers in parallel, it’s possible to handle large…
