<title>Example Architectures</title>
|
|
<para>To understand the possibilities OpenStack offers it's best to start
|
|
with basic architectures that are tried-and-true and have been tested
|
|
in production environments. We offer two such examples with basic pivots on
|
|
the base operating system (Ubuntu and Red Hat Enterprise Linux) and the
|
|
networking architectures. There are other differences between these two
|
|
examples, but you should find the considerations made for the choices in each
|
|
as well as a rationale for why it worked well in a given environment.</para>
|
|
<para>Because OpenStack is highly configurable, with many different
|
|
back-ends and network configuration options, it is difficult to write
|
|
documentation that covers all possible OpenStack deployments. Therefore,
|
|
this guide defines example architectures to simplify the task of
|
|
documenting, as well as to provide the scope for this guide. Both of the
|
|
offered architecture examples are currently running in production and
|
|
serving users.</para>
|
|
<tip><para>As always, refer to the Glossary if you are unclear about any of the
|
|
terminology mentioned in these architectures.</para></tip>

<title>Parting Thoughts on Architectures</title>
|
|
<para>With so many considerations and options available our hope is to
|
|
provide a few clearly-marked and tested paths for your OpenStack
|
|
exploration. If you're looking for additional ideas, check out the
