Infos

This book provides readers with an overview of Cloud Computing, starting with historical background on mainframe computers and early networking protocols, leading to current concerns such as hardware and systems security, performance, emerging areas of IoT, Edge Computing etc.  Readers will benefit from the in-depth discussion of cloud computing usage and the underlying architecture, with focus on best practices for using a dynamic cloud infrastructure, cloud operations management and cloud security.  The authors explain carefully the 'why's and how's' of Cloud Computing, so engineers will find this book and invaluable introduction to the topic.

Naresh K. Sehgal has been working at Intel since 1988, prior to that completed his B.E. from Punjab Engineering College (India), M.S. and Ph.D. from Syracuse University (New York). Naresh has taught a Cloud Computing class at Santa Clara University (California), where he also earned a MBA.

Pramod Chandra (PCP) Bhatt started his teaching career in 1965 at IIT Kanpur, and then moved to IIT Delhi in 1969, and retired from IIT Delhi in 1996. Prof Bhatt also worked as a visiting professor at the University of Ottawa, McGill University, Montreal (Canada), Universities of Dortmund, Paderborn and Bochum (Germany), Kochi University of Technology (Japan), Indian Institute of Information Technology (IIIT) and Indian Institute of Science (IISc) at Bangalore. Professor Bhatt has a M.E. from Calcutta University and a PhD from IIT Kanpur. He has also been a Konrad Zuse Fellow at the University of Dortmund.
