● Increase robustness – better services in each region – caches,
mirrors
● Increase coverage – Tempest integration, upgrade testing
● Increase integration with regular -infra tooling like logstash
● Monitoring of the region
● Quintupleo – run TripleO entirely within Nova and Neutron

Juno Other bits
● Renaming 'undercloud' and 'overcloud' to reduce confusion:
– Deployer / deployment cloud
– Workload cloud(s)
● KVM / Docker / LXC hypervisors in the deployment cloud
– Less overhead in small environments
– Faster reboots/redeploys of workload control plane nodes
