He likes the aspect of nova-docker that allows you to scale<br>(essentially) infinitely almost instantly, assuming you are using a<br>large pool of compute hosts. In the case of Magnum, if I'm a container<br>user, I don't want to be paying for a ton of vms that just sit idle, but<br>I also want to have enough vms to handle my scale when I infrequently<br>need it. But above all, when I need scale, I don't want to suddenly have<br>to go boot vms and wait for them to start up when I really need it.<br><br>I saw [1] which discusses container scaling, but I'm thinking we can<br>take this one step further. If I don't want to pay for a lot of vms when<br>I'm not using them, could I set up an autoscale policy that allows my<br>cluster to expand when my container concentration gets too high on my<br>existing cluster? It's kind of a case of nested autoscaling. The<br>containers are scaled based on request demand, and the cluster vms are<br>scaled based on container count.<br><br>I'm unsure of the details of Senlin, but at least looking at Heat<br>autoscaling [2], this would not be very hard to add to the Magnum<br>templates, and we would forward those on through the bay API. (I figure<br>we would do this through the bay, not baymodel, because I can see<br>similar clusters that would want to be scaled differently).<br><br>Let me know if I'm totally crazy or if this is a good idea (or if you<br>guys have already talked about this before). I would be interested in<br>your feedback.<br><br>[1]</font><u><font size="4" color="#0000FF"><br></font></u><a href="http://lists.openstack.org/pipermail/openstack-dev/2015-November/078628.html" target="_blank"><u><font size="4" color="#0000FF">http://lists.openstack.org/pipermail/openstack-dev/2015-November/078628.html</font></u></a><font size="4"><br>[2] </font><a href="https://wiki.openstack.org/wiki/Heat/AutoScaling#AutoScaling_API" target="_blank"><u><font size="4" color="#0000FF">https://wiki.openstack.org/wiki/Heat/AutoScaling#AutoScaling_API</font></u></a><font size="4"><br><br>--<br>Thanks,<br><br>Ryan Rossiter (rlrossit)<br><br><br>__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)</font><br><font size="4">Unsubscribe: </font><a href="mailto:OpenStack-dev-request@lists.openstack.org"><u><font size="4" color="#0000FF">OpenStack-dev-request@lists.openstack.org</font></u></a><font size="4"><mailto:</font><a href="mailto:OpenStack-dev-request@lists.openstack.org"><u><font size="4" color="#0000FF">OpenStack-dev-request@lists.openstack.org</font></u></a><font size="4">>?subject:unsubscribe</font><u><font size="4" color="#0000FF"><br></font></u><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev" target="_blank"><u><font size="4" color="#0000FF">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</font></u></a><font size="4"><br><br><br><br><br>__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)<br>Unsubscribe: </font><a href="http://OpenStack-dev-request@lists.openstack.org?subject:unsubscribe" target="_blank"><u><font size="4" color="#0000FF">OpenStack-dev-request@lists.openstack.org?subject:unsubscribe</font></u></a><u><font size="4" color="#0000FF"><br></font></u><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev" target="_blank"><u><font size="4" color="#0000FF">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</font></u></a><font size="4"><br></font></ul><font size="4"><br><br><br>-- </font><br><font size="4">Thanks,<br></font><br><font size="4">Jay Lau (Guangya Liu)</font><tt>__________________________________________________________________________<br>OpenStack Development Mailing List (not for usage questions)<br>Unsubscribe: OpenStack-dev-request@lists.openstack.org?subject:unsubscribe<br></tt><tt><a href="http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev">http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev</a></tt><tt><br></tt><br><BR>
