You understand the benefits of using all kinds of flexible cloud computing models and are ready to move forward with a development and deployment platform that gives your organization a competitive advantage. ✓ You’re a business leader who wants IT resources to be a utility that’s optimized to leverage what you’ve already paid for. You want IT to serve your business needs — to execute your strategies on your timetable — and to be your partner in innovating for the future. ✓ You’re an IT leader who knows a lot about technology but aren’t sure precisely how PaaS works. You need to understand how PaaS changes IT and what you need to do to support the business with cloud computing as an important enabler. How This Book Is Organized This book isn’t intended to be an exhaustive technical manual on implementing and managing cloud computing. Instead, it gives you a taste of the concepts and approaches you need to consider when embarking on your journey to PaaS. We’ve organized this book into five chapters: ✓ Chapter 1 gives you an overview of the fundamentals of cloud computing, including Infrastructure as a Service (IaaS), Software as a Service (SaaS), and PaaS. ✓ Chapter 2 provides you with an understanding of the way PaaS helps address IT challenges, and it lays out the different approaches of PaaS and how it helps streamline development and IT operations.
