1 Introduction
The aim of this guide is to provide a practical reference to help enterprise information
technology (IT) and business decision makers adopt cloud computing to solve business
challenges and to act as a readymade guide before undertaking Cloud Outsourcing. The
emergence of cloud computing, like any new technology model, has the side effect of flooding
the market with information and jargon that adds to the confusion and uncertainty among
decision makers. The ―Practical Guide to Cloud Computing‖ aims to remedy this by providing
comprehensive and actionable information in a single reference.
The guide explains in nontechnical language the key concepts of cloud computing and how best
to adopt cloud solutions to solve specific enterprise problems. The Practical Guide to Cloud
Computing contains a set of guidelines and strategies to help decision makers in all major
activities related to implementing cloud solutions. For example, the ―Rationale for Cloud
Computing‖ section explains the different types of cloud service models (Infrastructure as a
Service, Software as a Service, and Platform as a Service) and deployment models (private,
public, community, and hybrid). This section also describes specific costs and benefits of each
cloud model with respect to enterprise business challenges. The ―Cloud Computing Vision‖
section looks into the future evolution of the cloud. It provides a vision on the potential uses and
benefits of cloud as the technology matures
