RabbitMQ Essentials - Second Edition

By: Lovisa Johansson, David Dossot

Overview of this book

RabbitMQ is an open source message queuing software that acts as a message broker using the Advanced Message Queuing Protocol (AMQP). This book will help you to get to grips with RabbitMQ to build your own applications with a message queue architecture. You’ll learn from the experts from CloudAMQP as they share what they've learned while managing the largest fleet of RabbitMQ clusters in the world. Following the case study of Complete Car, you’ll discover how you can use RabbitMQ to provide exceptional customer service and user experience, and see how a message queue architecture makes it easy to upgrade the app and add features as the company grows. From implementing simple synchronous operations through to advanced message routing and tracking, you’ll explore how RabbitMQ streamlines scalable operations for fast distribution. This book will help you understand the advantages of message queue architecture, including application scalability, resource efficiency, and user reliability. Finally, you’ll learn best practices for working with RabbitMQ and be able to use this book as a reference guide for your future app development projects. By the end of this book, you’ll have learned how to use message queuing software to streamline the development of your distributed and scalable applications.

Using RabbitMQ in real life

The most common use case for RabbitMQ is a single producer, single consumer queue. Think of it as a pipe where one application puts messages into one end of the pipe and another application reads the messages that come out the other end. Messages are delivered in first in, first out order. These messages may be commands or contain important data. This sounds easy, but where could this type of architecture be applied? It's time to understand when and why message queuing shines!

Message queues between microservices

Message queues are often used in between microservices, but what does that mean?

Microservice architectural style divides the application into small services, with the finished application being the sum of its microservices. The services are not strictly connected to each other. Instead, they use, for example, message queues to keep in touch. One service asynchronously pushes messages to a queue and those messages are delivered to the correct...
