Full outline finished. Keystone, Glance, and most of Nova complete Changes to Common: * Separate "Getting Started" content into separate files, so they can be included individually where needed in the install guide * separated "Keystone Concepts" so that a smaller subset of that can be used in the install guide Change-Id: I583349443685e3022f4c4c1893c2c07d1d2af1d5

<title>Orchestration Service</title>
|
|
<para>The Orchestration Service provides a template-based
|
|
orchestration for describing a cloud application by running
|
|
OpenStack API calls to generate running cloud applications.
|
|
The software integrates other core components of OpenStack
|
|
into a one-file template system. The templates enable you to
|
|
create most OpenStack resource types, such as instances,
|
|
floating IPs, volumes, security groups, users, and so on.
|
|
Also, provides some more advanced functionality, such as
|
|
instance high availability, instance auto-scaling, and nested
|
|
stacks. By providing very tight integration with other
|
|
OpenStack core projects, all OpenStack core projects could
|
|
receive a larger user base.</para>
|
|
<para>Enables deployers to integrate with the Orchestration
|
|
Service directly or through custom plug-ins.</para>
