On this specific point, something we have discussed a few times now is
the idea of fronting a cloud with a consolidated HAproxy pair; in this
deployment scenario all API service charms would relate to a shared
haproxy deployment rather than/as well as using the embedded
haproxy/corosync/pacemaker feature that we currently have in the
charms;  this has the disadvantage of routing all public endpoint
traffic through a single point, but would help alot with public IPv4
address consolidation and ingress management into your cloud from the
Internet

Any thoughts?
