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 federated brokers and log aggregation

The way a cluster of two RabbitMQ brokers is created is really similar to what is typically done when making a relational database highly available. The database remains a centralized resource offering high guarantees of availability. Still, RabbitMQ is not a one-trick rabbit when it comes to high availability.

To form a picture of a RabbitMQ system, the following two plugins allow broker connection:

Shovel: Connects queues and exchanges between different brokers
Federation: Forms cross-broker connections for queues to queues, or exchanges to exchanges

Both plugins ensure the reliable delivery of messages across brokers by routing them as instructed or offering a safe place for them to remain until they can be dealt with. Neither requires the brokers to be clustered, which simplifies setup and management. Moreover, both plugins work fine over WAN connections, which isn't the case in a clustering scenario.
