I would like to thank my grandmother, Tayamma, for raising me to be helpful to others by sharing my knowledge in every possible way. She was the one who always taught me how to put in serious effort with 100% dedication, and not worry much about results. Therefore, I dedicate this book to her, to my inspiration.
I also cannot understate the support given by my father, Venkataiah Yellavula; mother, ShobaRani Dasyam; and lovely younger brother Saikiran, who understood the value of the time I spent on this book and always encouraged me with their positive wishes. I am grateful to my mentor, Chandrashekar MuniBudha, Solutions Architect, Amazon Web Services, whom I am deeply indebted to. I also thank Ashwin Baskaran, Senior Director, Citrix, who encouraged and pushed me forward in all possible ways. Thank you!
I cannot name everyone here; the list is so big. However, I sincerely thank all my friends who always wished success for this book.
