I had the pleasure to be a technical reviewer for the book, Enterprise Integration with WSO2 ESB from Packt Publishing. This book describes few common enterprise integration patterns using WSO2 ESB. Below are some notes from a technical point of view regarding the book.
Due to the fact the book is a self introductory text and starts with a gentle introduction to WSO2 ESB, it can be followed easily by any new comer. It doesn't assume any previous knowledge on the product. Due to the richness of configuration language of the product, readers don't need to aware of any programming language. The book starts with a guide on how to set up the product so that the readers can try out the configurations in later chapters.
The book covers the most of the common integration patterns such as(but not limited to) content based routing, dynamic routing, scatter and gather, publish/subscribe, service chaining and detour. The book also provides complete ready to use configurations for message transformations, enterprise messaging, protocol and transport switching. And also the book provide complete configurations for each scenario that it describes. These configurations can be used as the building blocks of the real world use cases. Because of each chapter is independent from each other readers can read only the required materials and start solving the business use case using WSO2 ESB quickly and without much effort.
Finally the book also covers how to deploy WSO2 ESB in a production environment and also how to fine tune for the same environment for optimal resource utilization and high performance.
