I am indebted to many. First of all, I would like to thank my mother, Anbuselvi, and grandmother, Saraswathi, for their endless effort and perseverance in bringing me up to this level. I am thankful to the entire team at Packt for accepting my proposal in bringing out a book of this kind. I would like to especially mention Meeta, Neil, and Amigya for their valuable guidance throughout the writing of the manuscript.

I am very grateful to my technical reviewers, Oscar Campos, and Jibo He, for reviewing the manuscript and providing me with constructive feedback that helped me shape the content. I would also like to extend my sincere gratitude to my professors, Senthil Kumar, and Radhika, for guiding me and encouraging me in all my spheres of life. I would not be very kind if I missed thanking my sister, Kamala, and my aunt, Kalavathi, for all the hope and love they have towards me.

I would also like to thank all my friends and brothers as their list is too big to mention here. They all have been my well-wishers and helped me in my tough times. I have missed many people here, but my thanks are always due to them who directly or indirectly influenced my life.

Above all, thanks to The Almighty for the showers of blessings on me.
