I agree with this sentiment. I’d just like to pull-up to the decision level, and if we can get some consensus on how we move forward, we can bring a concrete plan to the summit instead of 40 minutes of Kumbaya. We love each other. Check. Things are going to change sometime. Check. We might spin-out someday. Check. Now, let’s jump to the interesting part. > 3.

If all of advanced services spins out, I see that There is merit here, but consider the sorts of things that an advanced services framework should be doing: - plugging into neutron ports, with all manner of topologies - service VM handling - plugging into nova-network - service chaining - applying things like security groups to services … this is all stuff that Octavia is talking about implementing itself in a basically defensive manner, instead of leveraging other work. And there are specific reasons for that. But, maybe we can at least take steps to not be incompatible about it. Or maybe there is a hierarchy of Neutron -> Services -> LB, where we’re still spun out, but not doing it in a way that we have to re-implement the world all the time. It’s at least worth a conversation or three. Thanks, Doug On 10/26/14, 6:35 PM, "Brandon Logan" <brandon.lo...@rackspace.com> wrote: >Good questions Doug. My answers are as follows: > >1. Yes >2.
