WSO2 ESB is one of the leading ESBs out there in terms of features, scalability, and performance. It's being battle-tested at eBay and many other Fortune 100 companies. At the time of this writing, eBay is handling more than 4 billion transactions per day through the WSO2 ESB. In this book, I will cover some of the key features of WSO2 ESB mostly used in enterprise integration. Each feature is covered at the introductory level, to help anyone who is not that familiar with the WSO2 ESB, to catch up and proceed.
I would first like to thank, Vinay Argekar, an Acquisition Editor at Packt Publishing who came up with the idea of writing a book on the most popular WSO2 product—undoubtedly the ESB. Then, I would like to thank Sneha Modi, Priyanka Shah, Subho Gupta, Romal Karani, Tanvi Bhatt, and all the others from Packt Publishing who helped me throughout to make this book a reality from the initial idea. Thank you very much for all your continuous support.
If not for Dr. Sanjiva Weerawarana and Paul Fremantle we wouldn't have had a WSO2 ESB today to talk about. They founded WSO2 in 2005 with a mission to build a new era for SOA, and WSO2 ESB is a key ingredient. Today WSO2 provides a fully open source platform with more than 16 products. I am truly grateful to both Dr. Sanjiva and Paul for everything they have done for this field and for the community. And also, for mentoring and moulding me with care and patience.
Also, I would like to thank Samisa Abeysinghe, who is our VP, Training at WSO2 for being a great mentor to me throughout all these years.
My beloved wife, Pavithra. She wanted me to write this book even more than I wanted to. If I say she is the driving force behind this book, I am not exaggerating. She simply went beyond just feeding me with all the encouragement, but also helped immensely in reviewing the book and developing samples. She was the first reader, as always. Thank you very much Pavithra.
Kasun Indrasiri, who is the Product Manager and the Architect of WSO2 ESB, added so much value to the book with his technical expertise by reviewing the book. Thank you very much Kasun. I would also like to thank Rajika, Kishanthan and Charitha for reviewing the book for technical accuracy. Your inputs are highly appreciated.
Miyuru Daminda, Dushan Abeyruwan, Isuru Udana, and all the members of the WSO2 ESB team helped me a lot, clarifying all my doubts related to the product internals. Thank you very much, I appreciate your help a lot.
Last, but not least, my parents and my sister are the driving force behind me all the time since my birth. If not for them I wouldn't be who I am today. I am so very grateful to them for leading my way to write my first book.
Although this sounds like a one-man effort—it's a team. I would like to thank everyone who supported me in different ways.
