Hi,<div><br></div><div>For the cloud controller, use 2 machines with a pacemaker setup with those resource agents. Simple as that.</div><div>We have 2 branches, one for Essex and one for Folsom.</div><div><br></div><div><a href="https://github.com/madkiss/openstack-resource-agents" target="_blank">https://github.com/madkiss/openstack-resource-agents</a><br>

<div style="word-wrap:break-word">Hey Edwards, <div>that is a concern many arise, today, there is not any both answer and implementations that would allow you to setup such.</div><div>One approach is to work with stateless instances - using an orchestration tool such a Puppet of Chef, which would take care by itself of the spawning and restoration. It supposes to relegate all the data to the orchestration tool. In case a node fails, or even an instance - redeploying would take less time.</div>


<div>I myself encountered though some customers topology which don't fit such approach (critical databases, etc...) for such case, you can either prep. a sleeping instance in one another node or setup a data replication between X instances. Network-wise you can automate the floating ip allocation using a detection solution. </div>


<div>I think that feature (auto respawn) would come up soon (guys feel free to correct me), since this is a real concern.</div><div>Regards,</div><div>Razique</div><div><br><div><div>
