First and foremost, I would like to thank God. I could never have done this without the faith that I have in Him, the Almighty.

No one walks alone, and when one is walking the journey of life, you begin to thank those who joined you, walked beside you, and helped you along the way.

Many thanks to mom, papa, and my brother, Alankar; you all have been supreme. You have nurtured my learning and have always stood by me when things were odd or even. Thanks to my in-laws for giving wings to Richa.

Huge thanks to my wife, Richa, for inspiring me at every step, supporting my efforts, and encouraging me through the long journey. Thanks for having patience with me when I was facing yet another challenge in my life that reduced the amount of time I spent with you, and your sacrifice of all those weekends and vacations.

I would like to express my gratitude to Bill Swenton for all his support. I would like to take this opportunity to thank all those with whom I have worked in the past and those who have inspired me in one way or the other. Many thanks to Dean Welch, Vijay Navaluri, Prakash Devarakonda, Sebastiaan Dammann, Monique Albrecht, Nader Svärd, and Jugni for inspiring me.

Thanks to the reviewers who worked on this book. I would like to thank Rikshith Shetty, Binny Babu, Navu Dhillon, Larissa Pinto, Anthony Albuquerque, Menza Mathew, Akash Rajiv Sharma, and all the members of the Packt Publishing team for editing and polishing the book.

Last but not least, I beg forgiveness from all those who have been with me over the course of all these years and whose names I have failed to mention.
