Cloud Computing is now common place. From mobile phones to large-scale global operations, this technology has become an all-pervasive element. This book has been written keeping in mind the immediate needs to understand the topic by students, researchers, and IT professionals who seek to build and maintain a Cloud infrastructure. The text presented in the book serves to both highlight and explain how Cloud Computing functions. Given that Cloud Computing forms a vital backbone for almost all sizes of business globally, legal and audit issues are almost always closely watched for all types of deployments on Cloud. We discuss the areas of critical focus to empower readers with the understanding on legal and statutory requirements with respect to Cloud models. This book is more than a simple text book reference. It is meant to be a springboard for taking a giant leap into the Cloud.
