Typical cloud deployments - be it Openstack, Eucalyptus etc - have a separate control layer installed and upgraded using separate tools (which might be hand-configured PXE + preseeding, Cobbler, Orchestra/MAAS, FAI etc). As a result you have two distinct provisioning systems in play, which allows for more user error and increased special cases in automation. Using Openstack’s bare-metal hypervisor, my team are building a fully self contained cloud, where the control layer for the cloud is itself deployed and upgraded via the same cloud API.
Audiences should be anyone looking to deploy complex cloud applications, or anyone looking to deploy OpenStack. They should expect to leave the talk with all of their notions about large-scale application deployment stood soundly on their head.
