I would like to dedicate this book in the loving memory of my parents, C.O.Devassy and Elsy Devassy, whose steady, balanced, and loving upbringing has given me the strength and determination to be the person I am today. I would like to thank my wife, Anitha, for standing beside me throughout my career and for the effort she put in taking care of our son Heaven while I was writing this book. Also, I would like to thank my brothers Sible and Fr. Able Chirammal, without whose constant support this book would not have been possible.

Finally, a special thanks to Ulrich Obergfell for being an inspiration, which helped me enrich my knowledge in virtualization.
