To my wife, Maria Luisa, and my children, Gaia and Marco.

Gabriele Santomaggio has worked in the IT industry for more than 15 years. He is a developer, and very keen on middleware and distributed applications. Currently, he is working on high-performance Java applications.

He is the member of a big IT Italian community (www.indigenidigitali.com/) where he has published some posts about Amazon Web Services and message-oriented middleware (http://blog.indigenidigitali.com/tag/gabriele-santomaggio/).

He likes running and listening to jazz music.

To my beautiful wife, Dia, and my little ninja turtle, Riccardo, with love.

About the Reviewers

Jorge Puente Sarrín is a Peruvian software developer, currently working at Red Científica Peruana (RCP) as a software architect designing service-based solutions. He is a passionate developer focused on building distributed systems solutions using asynchronous programming with Python and .NET. Also, he has been contributing towards the translation of documentation projects and online courses into Spanish. He is a proud member of Masters of MongoDB, a group of persons who are promoting MongoDB around the world.

Ken Taylor has worked in software development and technology for over 15 years. During the course of his career, he has worked as a systems analyst on multiple software projects in several industries as well as with the state government. He has used RabbitMQ for messaging on multiple projects as a way of scaling and as an integration point. He is a member and speaker of the 757 Ruby users group and the Hampton Roads .NET users group (HRNUG). Ken holds an A.S. in Computer Science from Paul D. Camp Community College and was awarded a U.S. Patent for a Real Estate financial software product. He is currently working at Outsite Networks Inc. in Norfolk, Virginia. He lives in Suffolk, Virginia with his lovely wife Lucia and his two sons, Kaide and Wyatt.

I would like to thank my wife for her support while writing this book and my sons for reminding me of the importance of being inquisitive. Thank you Packt Publishing for asking me to participate as a technical reviewer for this excellent resource on RabbitMQ.

Ignacio Colomina Torregrosa is a technical engineer in telecommunications and a master in free software. He works as a PHP/Symfony developer and has had experience using RabbitMQ as a tool to optimize and improve the performance of web applications that deal with large amounts of traffic.

Héctor Veiga is a software engineer specializing in real-time data integration. Recently, he has focused his work on different cloud technologies (AWS, Heroku, OpenShift, and so on) to develop scalable, resilient, and high-performing applications that are able to handle high-volume, real-time data in diverse protocols and formats. Additionally, he has a strong knowledge of messaging systems, such as RabbitMQ and AMQP. Also, Héctor has a Master's degree in Telecommunication Engineering from the Universidad Politécnica de Madrid and a Master's degree in Information Technology and Management from the Illinois Institute of Technology.

Héctor currently works at HERE as part of Global Data Integration team and is actively developing scalable applications to consume data from several different sources. HERE heavily utilizes RabbitMQ to address their messaging requirements. In the past, Héctor has worked at Xaptum Technologies, a company dedicated to M2M technologies.

I would like to thank my family and friends for their support. They showed me that giving up was not an option and that you just need to keep pushing. Also, I am greatly thankful for the opportunity I was given to live and work in a foreign country. Finally, I would like to acknowledge Steve Fosdal who has been my friend and RabbitMQ colleague during this journey.

Preface

The RabbitMQ Cookbook covers RabbitMQ and the corresponding AMQP protocol.

Even the less-experienced programmer can find a lot of information that is useful to start developing messaging applications using RabbitMQ, especially in the first few chapters.

However, in order to fully appreciate some of the chapters of the book, the reader should also know the basic concepts about web and cloud applications.

The book is full of examples that show you how to use RabbitMQ in very disparate scenarios, in different technologies, right from single hosts to geographically replicated high-availability clusters. Mostly everyone working with these technologies will find a lot of useful information within this book.

What this book covers

Chapter 1, Working with AMQP, introduces the basic concepts of AMQP, the Advanced Message Queuing Protocol, on which RabbitMQ is based. It shows how the fire-and-forget messaging model works and how to use it from clients.

Chapter 2, Going beyond the AMQP Standard, covers the RabbitMQ extensions of AMQP and how they can be used to increase the efficiency of messaging applications.

Chapter 3, Managing RabbitMQ, explains how to configure RabbitMQ parameters, enable RabbitMQ plugins, and monitor RabbitMQ activities.

Chapter 4, Mixing Different Technologies, covers the integration of different technologies with other protocols, such as MQTT, STOMP, and JSON.

Chapter 5, Using RabbitMQ in Web Applications, shows how to develop web applications with RabbitMQ as a service bus.

Chapter 6, Developing Scalable Applications, explains how to create scalable and robust applications using RabbitMQ clustering.

Chapter 7, Developing High-availability Applications, covers the high-availability options offered by RabbitMQ.

Chapter 8, Performance Tuning for RabbitMQ, explains how to optimize the performance of applications based on RabbitMQ in different scenarios.

Chapter 9, Extending RabbitMQ Functionality, covers the use and development of RabbitMQ plugins.

Chapter 10, RabbitMQ on AWS, explains how to deploy RabbitMQ applications on Amazon Web Services.

Chapter 11, AMQP and Cloud Computing – RabbitMQ on PaaS, explains how to deploy and use RabbitMQ on Cloud Foundry.

Chapter 12, Managing RabbitMQ Error Conditions, explains how to diagnose and deal with RabbitMQ error conditions.

What you need for this book

You can use Linux/Unix, Mac OS X, or Windows as the operating system since RabbitMQ is cross-platform middleware. Most of the examples have been developed in Java, but to execute other recipes, you will also
