<p>Just to add a few things,<br>
</p>
<p>Barbican is not yet implemented in Octavia, though the code is there, we just need to spend a few hours hooking it all up and testing it out.<br>
</p>
<p><br>
</p>
<p>Also, the security groups are used by octavia right now so that only the ports on the listener are accessible. Basically if a loadbalancer has listeners on ports 80 and 443, the vip ports will only allow traffic on those ports. It shouldn't allow other
traffic.<br>

<p>Thanks,<br>

<div>Hi Maish,
<div class=""><br class="">
</div>
<div class="">Thanks for the feedback, some answers below. Please also be aware of the lbaas use cases session tomorrow at 9am (yuck, I know), <a href="https://etherpad.openstack.org/p/YVR-neutron-lbaas-use-cases" class="">https://etherpad.openstack.org/p/YVR-neutron-lbaas-use-cases</a></div>

<div bgcolor="#FFFFFF" class="">Hello all,<br class="">
<br class="">
Going over today's presentation "Load Balancing as a Service, Kilo and Beyond"[1] (great presentation!!) - there are a few questions I have regarding the future release:<br class="">
<br class="">
For Octavia 1.0:<br class="">
<br class="">
1. Can someone explain to me how the flow would work for spinning up a a new Amphora with regards to interaction between Neutron, LBaaS and Barbican?<br class="">
Same question as well regarding how the standby is created and its relationship with Barbican.<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>The lbaas API runs inside neutron-server. The general flow is:</div>
<div><br class="">
</div>
<div>- User interacts with neutron CLI/API or horizon (in liberty), and creates an LB.</div>
<div>- Lbaas plugin in neutron creates logical models, fetches cert data from barbican, and calls the backend lbaas driver.</div>
<div>- The backend driver does what it needs to to instantiate the LB. Today this is a synchronous call that waits for the nova boot, but by Liberty, it will likely be an async call to the octavia controller to finish the job.</div>
<div><br class="">
</div>
<div>Once Octavia has control, it is doing:</div>
<div><br class="">
</div>
<div>- Get REST calls for objects,</div>
<div>- Talk to nova, spin up an amphora image,</div>
<div>- Talk to neutron, plumb in the networks,</div>
<div>- Send the amphora its config.</div>
<br class="">

<div bgcolor="#FFFFFF" class=""><br class="">
2. Will the orchestration (Heat) also be implemented when Octavia 1.0 is released or only further down the line?<br class="">
If not what would you suggest be the way to orchestrate LBaaS until this is ready?<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>We need to talk to the Heat folks and coordinate this, which we are planning to do soon.</div>
<br class="">
<blockquote type="cite" class="">

<div bgcolor="#FFFFFF" class=""><br class="">
3. Is there some kind of hook into Security groups also planned for the Amphora to also protect the Load Balancer?<br class="">
</div>
</div>
</blockquote>
<div><br class="">
</div>
<div>Not at present, but I recorded this in the feature list on the etherpad above.</div>
<br class="">
<blockquote type="cite" class="">
<div class="">
<div bgcolor="#FFFFFF" class=""><br class="">
I think that based on the answers to these questions above - additional questions will follow.<br class="">
<br class="">
Thanks<br class="">
