Foreword
Welcome to RabbitMQ in Action. If you’re like me, possibly you’re thinking, “Should I read past page one?” Alas, too many technology books are written and published, and not all merit more than superficial attention. So let me invite you to read on, if you think this description fits you:
- You want a practical way to learn about push technology, streaming data, and other messaging patterns.
- You want to achieve professional-level expertise with RabbitMQ, including best practices for design and running in production.
In other words, this book is not just a guide to RabbitMQ. It teaches fundamental design patterns across many use cases. It shows why more applications are using them—and what the “dos” and “don’ts” are.
What are these patterns? If you’ve ever wanted to draw a picture of your system as an information flow or network, rather than as a stack, then you’re probably using messaging, or are ready to do so. You may be thinking of data delivery, nonblocking operations, or push notifications. Or you want to use publish/subscribe, asynchronous processing, or work queues. All of these are patterns, and they form part of the design canvas known as messaging.
