<para>Although most OpenStack architecture designs fall into one
|
|
of the seven major scenarios outlined in other sections
|
|
(compute focused, network focused, storage focused, general
|
|
purpose, multi-site, hybrid cloud, and massively scalable),
|
|
there are a few other use cases that are unique enough they
|
|
can't be neatly categorized into one of the other major
|
|
sections. This section discusses some of these unique use
|
|
cases with some additional details and design considerations
|
|
for each use case.</para>

packets directly from the wire or participating in

routing protocols.</para>

OpenStack installation.</para>
