Microservice Messaging with Kafka

This project showcases a fundamental Kafka architecture implemented with a producer and consumer in a microservices environment. It serves as a foundation for leveraging Kafka in event-driven communication.

Key Features:

• Docker Compose: Easily spin up a local Kafka and Zookeeper cluster.
• Producer (ApiGateway): Publishes messages to a topic ("transaction-topic").
• Consumer (ApiConsumer): Listens for messages and logs them.

Benefits:

• Decoupled Microservices: Services communicate asynchronously through events, enhancing independence and scalability.
• Scalability: Kafka efficiently handles high volumes of messages.
• Fault Tolerance: Messages are persisted, ensuring delivery even if services are unavailable.

Getting Started:

1. Clone the repository:

   git clone https://github.com/kay-verma/Microservice-Messaging-with-Kafka.git

2. Build and run Docker containers:

   docker-compose up -d

4. Run the producer (ApiGateway):

5. Run the consumer (ApiConsumer):

Further Development:

• Extend the consumer to perform actions based on message content (e.g., send emails, update databases).
• Implement complex workflows by chaining messages to other topics.
• Integrate with your existing microservices to enable event-driven communication.
