Acknowledgement

To my loving wife and dearest friend, Foke, without you I couldn't have achieved this hurdle. You are truly the crystal clear water that cleanses my soul. Also, I am thankful to my kids who have been patient while daddy was busy writing the book, even during Easter!

James Lumsden and other technical staff at Packt publishing for their patience, perseverance, and continued guidance in this journey of bringing to you all a collection of thoughts around a technology as I see it. James helped me in packaging it so you all could read comfortably without getting lost in the complex verbiage that I am sometimes prone to indulge in. The same also goes to the technical reviewers who helped me stay on track.
