All things Kafka

This article introduces Apache Kafka as a solution to tight coupling problems in microservices architectures, where synchronous communication causes cascading failures under heavy load. It explains Kafka's core concepts—Producers, Consumers, Topics, and Brokers—and how Kafka acts as a central message broker enabling event-driven, decoupled communication between services. The post also touches on Kafka's architecture including Partitions and Consumer Groups for scalability.
