<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>
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>General purpose: A cloud built with common
|
|
components that should address 80% of common use
|
|
cases.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Compute focused: A cloud designed to address compute
|
|
intensive workloads such as high performance computing
|
|
(HPC).</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Storage focused: A cloud focused on storage
|
|
intensive workloads such as data analytics with
|
|
parallel file systems.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Network focused: A cloud depending on high
|
|
performance and reliable networking, such as a content
|
|
delivery network (CDN).</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Multi-site: A cloud built with multiple sites
|
|
available for application deployments for
|
|
geographical, reliability or data locality
|
|
reasons.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Hybrid cloud: An architecture where multiple
|
|
disparate clouds are connected either for failover,
|
|
hybrid cloud bursting, or availability.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Massively Scalable: An architecture that is intended
|
|
for cloud service providers or other extremely large
|
|
installations.</para>
|
|
</listitem>
|
|
</itemizedlist>
|
|
<para>A section titled Specialized Use Cases provides information
|
|
on architectures that have not previously been covered in the
|
|
defined use cases.</para>
|
|
<para>Each chapter in the guide is then further broken down into
|
|
the following sections:</para>
