<strong>apocalyptic civics</strong>. Apocalyptic civics is the
insistence that we cannot ignore the truth, nor should we panic about
it. It is a shared consciousness that our institutions have failed and
our ecosystem is collapsing, yet we are still here — and we are creative
agents who can shape our destinies. Apocalyptic civics is the
conviction that the only way out is through, and the only way through is
together. "<br><br><i>Greg Bloom</i> @greggish <a href="https://twitter.com/greggish/status/873177525903609857" target="_blank">https://twitter.com/greggish/status/873177525903609857</a><br></div></div></div></div></div></div></div></div></div></div></div></div>

</span>We went with ansible at the end of 2015 until we hit a road block with<br>
it not using a client daemon a fat ferew months. When having a few 1000<br>
states to perform on each client, the lag for initiating the next state<br>
centrally from the server was quite noticeable - in the end a single run<br>
took more than half an hour without any changes (for a single host!).<br>
<br>
After that we re-evaluated with salt stack being the outcome scaling<br>
well enough for our O(2500) clients.<br>
<br>
Note, I ave not tracked if and how ansible progressed over the past<br>
~2yrs which may or may not exhibit the same problems today.<br>
<br>
Cheers<br>
