There are many people in my personal and professional life who made me what I am today. Though many of the names that I am going to mention in this book may not even know what AWS is, without their support, I would not have even developed many of the basic life skills, let alone the ability to write an AWS book.

First and foremost I would like to thank my father, who taught me how important it is to be a good human being before being anything in life. I will always be indebted to my mother, who taught me how to work hard and what strong willpower is. I would also like to mention my wife, Priya; without her support this book would not have been possible. My son, Arav, also deserves a special mention here, as I have spent some of his share of my time on this book.

I would also like to thank my sisters, Asha and Bina, who taught me what compassion is. I must thank my brother, Vijay, who has always protected me in every aspect of life.

I would also like to thank Badrinarayan Ramanujan, my friend, who has always motivated me and helped me assess my real value. Very special thanks as well to Jaymin Jhala as I don't think my IT career would have started without him.

I must thank my friend, Jay Punjani, my brother from another mother, who has taught me to dream big and understand unspoken words. I would also like to thank Mr BSGK Shastry, my Guru, who cultivated the professional approach in me.

I would also like to thank Mr. Ira Sheinwald, my friend and mentor, who showed confidence in me and gave me a chance to work on my first AWS project. Heartfelt thanks also goes to my friend, Shashikant Kuwar, along with Ira, as we have worked together to solve many technical and strategic challenges on AWS.

I must show my gratitude to Mr. Vivek Raju, my friend and mentor in my AWS journey. My AWS journey would not have been enriched without the support of Varun Dube and Vikas Goel.

My heartfelt thanks also go to my friends Satyajit Das, Jhalak Modi, Appasaheb Bagali, Ajaykumar Kakumanu, Pushpraj Singh, Chandrasekhar Singh, and Rakesh Sing, who have been part of my AWS certification journey. Also, very special thanks to Gajanan Chandgadkar, who has been with me in multiple counts for not only technically reviewing this book, but also for being there in my AWS certification journey. We all worked together for almost a year to get our five AWS certifications.

I would also like to thank Heramb Bhavsar, Abhishek Jadhav, Swathy Mohan, and the entire team at Packt for making this book a reality.

Last but not least, I would like to thank my friend and co-author of this book, Bhavin Parmar, who saw the dream of writing this book with me. If it was not for him, I would not have taken this book as a project.
