Thanks to my parents: my dad, the late Mr. Subramanyam, and my mom, Mrs. Surekha, who gave birth to me, and all the sacrifices they have made to raise me and my siblings. Without them I would not have gained the knowledge I have. Mom and dad, you have been there day after day, to make sure my life turned out this way. I miss you dad. Thanks for the support mom.

An important acknowledgement goes to my sweet and great wife, Mrs. Padma, without whom I would not have completed this book--she has been pushing and motivating me every day throughout the journey to complete this book. She compromised on the family time; at times I feel I have a warrior when she is next to me. Thanks for all your love and motivation my sweet wife. 

I can't explain how much my kids missed their dad's time over the course of writing this book. I was lucky to have my sweet kids, Dhrithi and Smrithi, who could understand and be supportive. They used to check with me about the progress of this book. Thanks kids, you are the sweetest. 

Thanks to my sisters, Ajitha and Aisu, who supported my growth and education throughout my life by providing guidance and support. Thanks for being my sisters.

My thanks to all my employers: Cognizant, PwC, Event Consulting, and Sathyam, for providing me an opportunity to work at an organization that has, either directly or indirectly, helped me gain the knowledge to write this book.

Thanks to all my colleagues, especially Mr. Raja Rangenathan and Mr. Praveen Challa, my friends, my family, and all others who have helped me either directly or indirectly to complete this book. 

Thanks to the Packt team for giving me this opportunity and help in all the stages of completing this book.

Last but not least, I cannot forget to thank Mr. Fred Luddy for creating such a wonderful product, ServiceNow.
