Foolish Assumptions
The information on these pages is useful to many people, but
we have to admit that we did make a few assumptions about
who we think you are:
✓ You’re already using various forms of cloud computing
and are planning a long-term strategy to move more of
your development and deployment of applications to the
cloud. 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.
