Cloud computing is the on demand availability of computing services such as servers, storage, databases, networking, software, analytics, and intelligence over the internet. It not only facilitates faster innovation and flexible resources but also offers economies of scale. It is cheaper, faster, more secure, reliable, efficient, and accessible compared to the traditional way of availing IT resources. Public cloud, private cloud, and hybrid cloud are the three ways to deploy cloud services. Public clouds are owned and handled by third-party cloud service providers whereas a private cloud is used exclusively by a single entity. Hybrid clouds are a mix of both public and private clouds. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of cloud computing. There has been rapid progress in this field and its applications are finding their way across multiple industries. This book is a resource guide for experts as well as students.
