3  Introduction How This Book Is Organized This book isn’t intended to be an exhaustive technical manual  on implementing and managing cloud computing.

We’ve organized this book into six chapters: ✓ Chapter 1 gives you an overview of the business case  for foundational cloud services — what it means to the  business and how these services support the overall IT  approach. ✓ Chapter 2 provides you with an understanding of the  technical foundation for IaaS and PaaS. The chapter  includes use cases that explain the business benefits to  the organization. ✓ Chapter 3 delves into the economics of cloud services.  The chapter explains the type of economic benefit you  gain from using foundational cloud services and how  they support changing business requirements. ✓ Chapter 4 provides an overview of managing cloud workloads and services. Many different types of workloads  need to be supported in the cloud. This chapter presents  the different workloads and how they need to be managed  to support IT and business needs.  ✓ Chapter 5 provides insights into the important issue of  security, governance, and cloud reliability. What does it  mean to have a secure cloud and how do you ensure that  your assets are safe? How do you have the right level of  support for governance rules that keeps your company  safe and in compliance? ✓ Chapter 6 gives you a roadmap for planning your journey  to the hybrid cloud from a best practices perspective.
