The Libra project seems to offer a more robust alternative, at least for scaling. The haproxy implementation in Neutron seems to continue to evolve (like with https://blueprints.launchpad.net/neutron/+spec/lbaas-ha-haproxy), but I'm wondering why we can't leverage Libra. The APIs are a bit different, but the goals look very similar, and there is a waste of effort with 2 different implementations. Maybe we could see a Libra driver for Neutron LBaaS for example?

:( I had no idea, Andrew!

I presume you meant you would *not* go as far as duplicative or
So, please don't take this the wrong way... but does anyone other than
HP run Libra? Likewise, does anyone other than Rackspace run Atlas?
I find it a little difficult to comprehend why, if Libra preceded work
on Neutron LBaaS, that it wasn't used as the basis of Neutron's LBaaS
work. I can understand this for Atlas, since it's Java, but Libra is
Python code... so it's even more confusing to me.
Granted, I don't know the history of Neutron LBaaS, but it just seems to
be that this particular area (LBaaS) has such blatantly overlapping
codebases with separate contributor teams. Just baffling really.
Any background or history you can give me (however opinionated!) would
be very much appreciated :)

Which large OpenStack companies? Are these companies currently deploying
