Writing a book is a gratifying as well as demanding experience and I thank my family for putting up with my late nights and weekends while I was working on this book. I would like to acknowledge my husband, Parikshat, and my in-laws for their support. Thank you Mansi for always being so positive and standing by me when times got tough! This is for my two little kids who are a constant source of inspiration for me, to believe in the power of dreams and work hard to achieve them.

I would like to extend my gratitude towards my parents, my brother Pranav and his family for their encouragement throughout the course of the book's development. I am blessed to be surrounded by a group of very supportive friends especially from my undergraduate school days and would like to thank them for their motivation. Words cannot express my gratitude to all my wonderful colleagues at Blue Jeans Network and I truly appreciate their enthusiastic support and good wishes.

Thanks to the staff at Packt Publishing, especially Vinay Argekar, Adrian Raposo, and Edwin Moses for contacting me, reviewing the content, and keeping track of the schedule. Last but not least, I take this opportunity to thank the reviewers, Masoud Kalali, Dustin R. Callaway, Kausal Malladi, and Antonio Rodrigues, for their invaluable feedback and attention to detail.
