"Inter-Cloud Resource Federation" which will enable resource sharing across cloud in distributed multi-site OpenStack clouds deployments. This service will run on top of OpenStack Cloud and fabricate different cloud (or data centers) instances in distributed
cloud setup. This service will work closely with OpenStack components (Keystone, Nova, Cinder....) to manage and provision different resources (token, VM, images, network .....). Alliance service will provide abstraction to hide interoperability and integration
complexities from underpinning cloud instance and enable following business use cases.</span><span style="color:black"><o:p></o:p></span></p>

</span><tt><span style="font-size:10.0pt;color:black">Hello, Dear TC and all, </span>
</tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">Large cloud operators prefer to deploy multiple OpenStack instances(as different zones), rather than a single monolithic OpenStack instance because of these reasons:</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">1) Multiple data centers distributed geographically;</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
</span><tt><span style="color:black">2) Multi-vendor business policy;</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
</span><tt><span style="color:black">3) Server nodes scale up modularized from 00's up to million;</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
</span><tt><span style="color:black">4) Fault and maintenance isolation between zones (only REST interface);</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">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.</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">We call this pattern as "OpenStack Cascading", with proposal described by [1][2]. PoC live demo video can be found[3][4].</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">Nova, Cinder, Neutron, Ceilometer and Glance (optional) are involved in the OpenStack cascading.
</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">Kindly ask for cross program design summit session to discuss OpenStack cascading and the contribution to Kilo.
</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">Kindly invite those who are interested in the OpenStack cascading to work together and contribute it to OpenStack.
</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
<br>
</span><tt><span style="color:black">(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 )</span></tt><span style="font-size:10.0pt;font-family:"MS Gothic";color:black"><br>
