<p>Hello, Joe,</p>
<p> </p>
<p>Thank your encourage and good suggestion. That means this thread is a good start.</p>
<p> </p>
<p>So if anyone has any doubts about OpenStack cascading, please following this thread, so that we can colloect all things could not be solved in the mail, and then discussed in the design summit session.</p>
<p> </p>
<p>Best Regards</p>

Hello, Dear TC and all,<br>
<br>
Large cloud operators prefer to deploy multiple OpenStack instances(as different zones), rather than a single monolithic OpenStack instance because of these reasons:<br>
<br>
1) Multiple data centers distributed geographically;<br>
2) Multi-vendor business policy;<br>
3) Server nodes scale up modularized from 00's up to million;<br>
4) Fault and maintenance isolation between zones (only REST interface);<br>
<br>
At the same time, they also want to integrate these OpenStack instances into one cloud. Instead of proprietary orchestration layer, they want to use standard OpenStack framework for Northbound API compatibility with HEAT/Horizon or other 3rd ecosystem apps.<br>
<br>
We call this pattern as "OpenStack Cascading", with proposal described by [1][2]. PoC live demo video can be found[3][4].<br>
<br>
Nova, Cinder, Neutron, Ceilometer and Glance (optional) are involved in the OpenStack cascading.<br>
<br>
Kindly ask for cross program design summit session to discuss OpenStack cascading and the contribution to Kilo.<br>

<div>Cross program design summit sessions should be used for things that we are unable to make progress on via this mailing list, and not as a way to begin new conversations. With that in mind, I think this thread is a good place to get initial feedback on
the idea and possible make a plan for how to tackle this.</div>

<br>
Kindly invite those who are interested in the OpenStack cascading to work together and contribute it to OpenStack.<br>
<br>
(I applied for ¡°other projects¡± track [5], but it would be better to have a discussion as a formal cross program session, because many core programs are involved )<br>
