</p></div></blockquote><div>What is the benefit in having SSL between Varnish and back-end? I'd assume that the entire environment is under your control, so there's no security improvement for this. To have SSL on the front-end, we use nginx in front of Varnish.</div><br><blockquote type="cite"><div><p><a href="http://2.Is">2.Is</a> it possible to disable back-end servers for maintenance without touching the config?<br>
</p></div></blockquote><div>We just stop the back-ends. We don't make any config changes.</div><br><blockquote type="cite"><div><p><a href="http://3.Is">3.Is</a> it possible to create statics to get a graph to see its load factor?<br>
<br></p></div></blockquote></div>Yes. We graph Varnish with Zabbix, and other people use other monitoring tools.</body></html>
