I want to load balance across multiple SIP / UDP Proxies located inside OpenStack Guest Instances.
In the non-(OS) Virtualized world, I would use a hardware Load Balancer using D(S)R to spray across the SIP Proxies. I did some looking at OpenStack LBaaS, as a one stop shop. As in, one place to do both route into the Cloud from the outside world and Load Balancing. Piecing the parts together, it seems that UDP won't be supported until the LVS plug-in is available, scheduled for the Juno release. Is there a recommended configuration for such a set-up? I've been searching around and haven't seem much. The OpenStack and LVS-Tun reference I see, is a RackSpace article, which also mentions that all servers need to be in the same Huddle. I see some concern with the LVS Director being on a Guest VM and resource issues - but this was years ago, and on another hypervisor. Would DSR (ARP issues) or even Tunneling (would tunneling need to be done in Neutron as well) work from 'real' hardware outside the cloud? Otherwise, are we talking Double NAT? That is, NAT through OpenStack and then NAT for LVS. (The the SIP Persistence Engine is a separate item to deal with.)
