Camel Design Patterns
Patterns, Principles, and Practices for Designing Apache Camel Applications
About the Book
- Camel 3.x Updated book is available on Educative. For up-to-date content, pick that.
- Camel 2.x This book on LeanPub and the hardcover print on Lulu.
There are great books about Apache Camel already, but this book is a little bit different. Here is why. Throughout the building of a Camel application, there are many levels of design decisions to be made. Knowing the Camel framework and the Enterprise Integration Patterns (EIPs) is a must, but not enough to design a real-world integration application. Mastering such applications requires an understanding of EIPs, messaging, Microservices, and SOA principles, and distributed system concepts as a whole.
Driven by real-world experiences, this book consolidates the most commonly used patterns and principles for designing Camel applications. For each pattern, there is a problem description with a context, a proposed solution, and Camel specifics, plus tips around the implementation. Patterns range from individual Camel route designs for happy path scenarios, to error handling and prevention practices, to principles used in the deployment of multiple routes and applications for scalability and high availability purposes.
The patterns listed here are not new; they are all over the Internet, described many times under various categories and names. Here they are described from a practical point of view with an emphasis on implementing these patterns in Apache Camel, rather than academical pattern definition. And lastly, this book is not a step-by-step guide for writing Camel routes. Instead, it is a series of high-level use cases demonstrating different patterns used for creating modern Camel applications. No code, just pragmatic theory.
I believe you will find this short and focused book useful.
