<font size=2 face="sans-serif">This sounds related to the discussion on
the 'Nova clustered hypervisor driver' which started at Juno design summit
[1]. Talking to another OpenStack should be similar to talking to vCenter.
The idea was that the Cells support could be refactored around this notion
as well. </font>
<br><font size=2 face="sans-serif">Not sure whether there have been any
active progress with this in Juno, though.</font>

[all] [tc] Multi-clouds integration by OpenStack cascading</font>
<br>
<hr noshade>
<br>
<br>
<br><tt><font size=2>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>
<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>
