CONTENTS

PREFACE

This book was motivated by the desire to help students and professionals explore and understand cloud computing. This book is designed for use as a primary textbook for a course in cloud computing or as a resource for professionals seeking to explore the latest advances in cloud services. It also acts as a launch pad for companies seeking to educate their IT professionals about the potential opportunities of cloud computing.

The book highlights the recent developments in distributed computing and it details the architecture, virtualization concepts, and security concerns of cloud computing. It also provides a detailed understanding of the benefits of cloud computing that can encourage enterprises to switch to the cloud.

A thorough understanding of the cloud and its business processes is required to make the transition to the cloud. A number of books cover the various aspects of cloud computing, but very few books incorporate such a wide variety of topics in such a structured format. In this book, each topic has been covered in detail in terms of scope, content, and also from an examination point of view. A number of research papers and eminent journals have been taken as references in order to ensure high quality content and authentic information.

Chapters 1 and 2: Provide a basic understanding of the computing paradigm and the concept of cloud computing.

Chapter 3: Describes virtualization technology and its applications.

Chapter 4: Gives a brief introduction to cloud computing, its architecture, and the Hadoop Distributed File System (HDFS).

Chapter 5: Deals with cloud management concepts like scalable, fault tolerance, resiliency, provisioning, asset management, cloud governance, high availability, disaster recovery, and multi-tenancy.

Chapter 6: Details cloud information security fundamentals, architecture, and challenges.

Chapter 7: Provides case studies on various cloud providers and cloud services.

CHAPTER 1

OVERVIEW OF THE COMPUTING PARADIGM

Automatic computing has changed the way humans can solve problems and the different ways in which problems can be solved. Computing has changed the perception and even the world more than any other innovation in the recent past. Still, a lot of revolution is going to happen in computing. Understanding computing provides deep insights and generates reasoning in our minds about our universe.

Over the last couple of years, there has been an increased interest in reducing computing processors powers. This chapter aims to understand different distributed computing technologies like peer to peer, cluster, utility, grid, cloud, fog and jungle computing, and make comparisons between them.
