Setting up Kafka and ZooKeeper for local development

Kafka plays a role in an event-driven system, facilitating smooth communication among different components. It enables services to communicate through message exchange, like how people use messaging apps to stay connected. This architecture promotes the development of scalable applications by allowing various parts of the system to function autonomously and respond promptly to events. We will also mention Kafka and its role in the Understanding Kafka brokers and their role in event-driven systems section in more detail.

Think of it as having a coordinator who assigns tasks and ensures operations. ZooKeeper is essential for managing the background processes that uphold Kafka’s stability and reliability during peak loads.
