<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif";color:#212121">That is great to hear. I assume that if we are using security groups we will also be able to define rules regarding which networks the listeners are allowed to accept traffic

<br>
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>
<br>
For Octavia 1.0:<br>
<br>
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>
Same question as well regarding how the standby is created and its relationship with Barbican.<o:p></o:p></span></p>
