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.

Explaining message queues

Smoke signals, couriers, carrier pigeons, and semaphores: if this was a riddle, the word messages would immediately spring to mind. Humanity has always had the need to connect, finding new ways to defy challenges posed by the distance between the different groups of people needing to communicate. Humankind has come a long way with modern technologies, but essentially, the basics remain. Senders, recipients, and messages are at the core of all our communication infrastructures.

Software applications have the same needs; systems need to communicate and send messages between each other. They sometimes need to be sure that the message that's been sent has reached its destination, and sometimes they need to receive an immediate response. In some cases, they may even need to receive more than one response. Based on these different needs, different styles of communication between systems have emerged.
