<div class="sreweekly-description">
<p>In this podcast episode, the panelists hold a retrospective for the snow-related delay of DevOps Days Baltimore. Toward the end they go into the idea of reliability and single points of failure with respect to conference planning. My favorite quote in the show, from Nell Shamrell-Harrington:</p>
<blockquote><p>Incident Management is never about technology — it&#8217;s a people.</p></blockquote>

<div class="sreweekly-description">
<blockquote><p>Beamer is a stateless datacenter load balancer supporting both TCP and Multipath TCP (MPTCP). It manages to keep the load balancers stateless by taking advantage of connection state already held by servers.</p></blockquote>
<p>Super-clever! The LB <em>does</em> keep state, but the size of the state is constant, unrelated to the number of connections flowing through it.</p>

<p>Sometimes it&#8217;s worthwhile to lay everything out and describe just exactly what we&#8217;re up against as SREs. The analogies here are pretty awesome. Read this for a hefty dose of cynicism about the state of our increasingly computer-driven world.</p>
