Writing this book would not have been possible without help of many people. We had a wonderful time while writing, which was mainly due to the skills support, dedication and motivation of people around us.

First of all, we are extremely thankful to Kundan Prakash, Ankur Agarwal and Shanmugadas Chembakassery Sivadasan, Suresh Viswanath for their continuous support and motivation from the time we started writing this book.

We are deeply thankful to the entire team at Packt Publishing, including Tushar, Parul, Narendra, Ritika, Smeet, Denim, Safis, Dhanya, Tejal, Jason and Arvind. We would like to extend our thanks to Content Development Editor, Yusuf and our Technical Editor Akansha. They have been very supportive and helpful from the beginning. Thank you all for your effort and dedication.

A sincere thanks to Michael Washington for their insightful and deep technical review. He helped us to identify and fill the gaps and improve the quality of the book.

We would like to thank Charul Pant and Akshay Dixit for their offline review of the book and sharing their feedback. It was extremely helpful to get some feedback from avid reader and technology geek like you people. Thank you very much for your time and help us improving the book over the period.

We spent time in writing when we should have sleeping, spending time with family or playing with our kids. We wouldn't have never been able to write this book without support from our family. Be it late night working or meeting over weekends, they supported us every bit and pieces.
