<title>How this book is organized</title>
|
|
<para>This book has been organized into various chapters that help
|
|
define the use cases associated with making architectural
|
|
choices related to an OpenStack cloud installation. Each
|
|
chapter is intended to stand alone to encourage individual
|
|
chapter readability, however each chapter is designed to
|
|
contain useful information that may be applicable in
|
|
situations covered by other chapters. Cloud architects may use
|
|
this book as a comprehensive guide by reading all of the use
|
|
cases, but it is also possible to review only the chapters
|
|
which pertain to a specific use case. When choosing to read
|
|
specific use cases, note that it may be necessary to read more
|
|
than one section of the guide to formulate a complete design
|
|
for the cloud. The use cases covered in this guide
|
|
include:</para>
