service is designed to provide "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.<o:p></o:p></span></p>

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