<div class="sreweekly-description">
<p>This quarter&#8217;s <em>Increment</em> issue is about Reliability, and I haven&#8217;t had this much fun since their <a href="https://increment.com/on-call/">first issue about on-call</a>. I&#8217;ll include a few of the articles here and more in later issues as I have a chance to review them.</p>

<div class="sreweekly-description">
<blockquote><p>Accepting that imperfect things still work is fundamental to preventing failures from becoming catastrophes.</p></blockquote>
<p>Understanding that no system is without errors is critical to building resilient systems.</p>

<div class="sreweekly-description">
<p>The very first sentence sets the tone, and I love it:</p>
<blockquote><p>Resilience is a process: something you must actively perform, not something you check off a list once.</p></blockquote>

<div class="sreweekly-title"><a href="https://increment.com/reliability/technical-incident-command/" target="_blank">[Increment: Reliability] Embrace your inner incident commander</a></div>
<div class="sreweekly-description">
<blockquote><p>Most of all, having an incident commander only works if everyone believes in the role. Someone stepping in to address a crisis and saying “I’m Batman” doesn’t help unless people have bought into the idea of Batman.</p></blockquote>
<p>The next time I&#8217;m incident commander, I am <em>totally</em> going to jump in and say, &#8220;I&#8217;m Batman!&#8221;.</p>
<p>This article is a great primer on what an IC is and how to adopt incident command at your organization.</p>

<blockquote><p>After reading this blog post, you will have an understanding of the retry pattern used in microservices architecture, why it should be used, a few considerations while using the retry pattern, and how to use it in Python.</p></blockquote>
