There is a famous saying in India, Matha, Pitha, Guru, Deivam, which sets the order in which a person must show respect, starting with Matha (mother), and going on to Pitha (father), then Guru (teacher), and finally, Deivam (God).

First and foremost, I would like to thank my parents, Mr. BN Mohanram and Mrs. S Rajeswari, for laying the foundation of the core values required to become a responsible citizen. I have no words to explain the extensive support provided by them in every stage of my life; all I can say is that I am blessed to have them as my parents.

My teachers, Dr. SM Kannan and the late Dr. Sri Krishna, from KLN College of Engineering, incubated the desire for knowledge and innovation in me. I would like to thank them for their guidance and also for giving me opportunities on several occasions to interact with the young engineers of my college, be it as a guest lecturer or during brainstorming discussions on the latest technology trends.

"A woman not only protects herself but tirelessly takes care of her husband and preserves the family reputation." I would like to thank my wife, Mrs GL Lakshmi, for taking care of me and my family without any expectations. My special thanks to my daughters for sacrificing some of their play time so as not to disturb me while I wrote this book.

I would like to thank Packt for giving me this opportunity. My special thanks to Packt team members, Mr. Anurag Ghogre, Mr. Vikas Tiwari, Mr. Ulhas Kambali, and Mr. Denim Pinto for their extensive support whenever required. My sincere thanks to the technical reviewer, Mr. Mohamed Sanaulla, for detailed feedback on all the chapters and ensuring the quality of the content. My special thanks to my colleague Mr. Raja Malleswara Rao Pattamsetti for connecting me with Packt.

My sincere thanks to my elder brother, Mr. BM Karthikeyan, my relatives, and my friends for their unconditional support and well wishes.

Finally, I strongly believe all this has been possible only with the blessings of the Almighty. My thanks to the Almighty and I hope he brings peace and prosperity to this planet.
