Understanding and installing Apache Kafka

Apache Kafka is an open-source platform that handles real-time data streams. Originally designed as a messaging queue, it has evolved into a robust system for streaming data and building event-driven architectures. Communication between microservices is crucial, and that’s where Kafka shines.

Kafka itself is a huge concept that needs a different book. In this book, we’re going to provide enough information that we’ll be able to integrate and use it for our microservices. For more detailed information, you can follow my Apache Kafka for Distributed Systems course on the Udemy platform (https://www.udemy.com/course/apache-kafka-for-distributed-systems/).

Kafka uses a publish-subscribe messaging model. Services, acting as producers, publish events to specific channels known as topics within Kafka. Other services, functioning as consumers, subscribe to relevant topics and receive these events asynchronously.
