Introduction

RabbitMQ is an open-source message broker that facilitates asynchronous communication between applications or services in a distributed system. It supports various messaging protocols and is widely used for enabling message queuing and delivering messages between services in a decoupled manner. RabbitMQ ensures reliable, scalable, and fault-tolerant communication, providing features such as message routing, queuing, and persistence. It plays a vital role in microservices architectures, event-driven systems, and scenarios where decoupling between services is essential for scalability and performance.

Prerequisites

• Basic understanding of message brokers and asynchronous messaging concepts.
• Familiarity with message queuing and pub-sub (publish-subscribe) patterns.
• Knowledge of networking and distributed systems concepts.
• Understanding of a programming language like Python, Java, or JavaScript for integrating RabbitMQ.
• Familiarity with system administration for managing RabbitMQ in production environments.
