Foreword
As organizations have evolved over the last 40 to 50 years, they have slowly but steadily
found ways and means to improve their operations by adding IT/software systems across
their operating areas. It would not be surprising today to see more than 250+ applications in
each of our Fortune 200 companies. This has also slowly caused another creeping problem
as we evolve from our level of maturity to another; silos of systems that don’t interface well
to each other.
As enterprises move from local optimization to enterprise optimization they have been
leveraging some of the emerging technologies like Big Data systems to find ways and
means by which they could bring data together from their disparate IT systems and fuse
them together to find better means of driving efficiency and effectiveness improvement that
could go a long way in helping enterprises save money.
Tomcy and Pankaj, with their vast experience in different functional and technical domains,
have been working on finding better ways to fuse information from variety of applications
within the organization. They have lived through the challenging journey of finding a ways
to bring out changes (technological & cultural).
This book has been put together from the perspective of software engineers, architects and
managers; so it’s very practical in nature as both of them have lived through various
enterprise grade implementation that adds value to the enterprise.
Using future proof patterns and contemporary technology concepts like Data Lake help
enterprises prepare themselves well for the future, but even more given them the ability to
look across data that they have across different organizational silos and derive wisdom
that’s typically lost in the blind spots.

About the Authors
Tomcy John lives in Dubai (United Arab Emirates), hailing from Kerala (India), and is an
enterprise Java specialist with a degree in engineering (B Tech) and over 14 years of
experience in several industries. He's currently working as principal architect at Emirates
Group IT, in their core architecture team. Prior to this, he worked with Oracle Corporation
and Ernst & Young. His main specialization is in building enterprise-grade applications and
he acts as chief mentor and evangelist to facilitate incorporating new technologies as
corporate standards in the organization. Outside of his work, Tomcy works very closely
with young developers and engineers as mentors and speaks at various forums as a
technical evangelist on many topics ranging from web and middleware all the way to
various persistence stores. He writes on various topics in his blog
and www.javacodebook.com.
First and foremost, I would like to thank my savior and lord, Jesus Christ, for giving me
strength and courage to pursue this project. It was a dream come true.
I would like to dedicate this book to my father (Appachan), Late C.O.John, and my dearest
mom (Ammachi), Leela John, for helping me reach where I am today. I would also like to
take this opportunity to thank my dearest wife, Serene and our two lovely children, Neil
(son) and Anaya (daughter), for all their support throughout this project and also for
allowing me to pursue my dream and tolerating not being with them after my busy day
job.
It was my privilege working with my co-author, Pankaj. I take this opportunity to thank
him for supporting me, when I first offloaded my dream of writing this book topic and then
staying with me at all stages in completing this book. It wouldn't be possible to reach this
stage in my career without mentors at various stages of my career. I would like to
thank Thomas Benjamin (CTO, GE Aviation Digital), Rajesh R.V (chief architect,
Emirates Group IT) and Martin Campbell (chief architect) for supporting me at various
stages, with words of encouragement and wealth of knowledge.
