As the adoption of cloud technologies has skyrocketed, the need for a definitive, comprehensive guide on the subject has never been greater. Edited by leading authorities in the field——the book "Cloud Computing: Principles and Paradigms" is widely considered a cornerstone text in computer science literature. Published by John Wiley & Sons, Inc. , the book (first published in 2011 and available in a 2021 edition as well) aims to capture the state-of-the-art in cloud technologies and applications. Cloud Computing represents a paradigm shift from local
