Event-driven microservices are a design pattern for building scalable and resilient software systems. Instead of traditional monolithic architecture where all components are tightly coupled and execute in a predefined sequence, event-driven microservices decouple individual components and allow them to communicate and collaborate through the exchange of events.

This article is a condensed version of the video below.

In an event-driven microservices architecture, each microservice is designed to be small, modular, and independent, and it focuses on a specific business capability or functionality. These microservices communicate with each other through a messaging system, such as Apache Kafka, that acts as a central hub for exchanging events. This allows microservices to be loosely coupled and enables them to be developed, deployed, and scaled independently of one another.

One of the benefits of using event-driven microservices is that it enables the creation of highly scalable and resilient systems. Because each microservice is…
