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.

A RabbitMQ scenario

CC is a new taxi agency with huge potential. Today, the company has just two taxi drivers and two developers, but they want to expand a lot in the upcoming year. CC has already built a website in Ruby and started out with a backend, also written in Ruby, that stores CC trips in a database. CC also has some scripts, written in Python, that generate route reports.

So far, CC's system runs as follows:

  • The company's website and blog runs on Ruby.
  • The Rich Internet Application that stores route data, such as the starting point and the endpoint of the trip, is written in Ruby.
  • There's a back-office that sends route updates to drivers and is written in Ruby.
  • Multiple ad hoc Python scripts are used to extract and message data to generate route reports.
  • Taxi applications are written in Python.

The old architecture is illustrated as follows:
