<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 backends
|
|
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>

|
|
are unclear about any of the terminology mentioned in these
|
|
architectures.</para>

<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 <xref
