<title>Introduction</title>
<para>OpenStack is a leader in the cloud technology gold rush, as
organizations of all stripes discover the increased
flexibility and speed to market that self-service cloud and
Infrastructure-as-a-Service (IaaS) provides. However, in order
to reap those benefits, the cloud must be designed and
architected properly.</para>
<para>A well-architected cloud provides a stable IT environment
that offers easy access to needed resources, usage-based
expenses, extra capacity on demand, disaster recovery, and a
secure environment. A well-architected cloud does not
magically build itself. It requires careful consideration of a
multitude of factors both technical and non-technical.</para>
<para>There is no single architecture that is "right" for an
OpenStack cloud deployment. OpenStack can be used for any
number of different purposes, each with its own
particular requirements and architectural
peculiarities.</para>
<para>This book is designed to examine some of the most common
uses for OpenStack clouds (and some less common uses)
and to provide knowledge and advice to help explain the
issues that require consideration. These examples, coupled
with a wealth of knowledge and advice will help an organization
design and build a well-architected OpenStack cloud to fit its unique
requirements.</para>
<para><glossterm>OpenStack</glossterm> is a fully-featured, self-service
cloud. Consider the design of your cloud carefully so that it will
accurately suit your needs.</para>
<para>This book examines some of the most common uses for OpenStack clouds, and
explains the considerations for each use case.</para>
