<div class="sreweekly-description">
<blockquote><p>Reliability is something you do, not something you buy.</p></blockquote>
<p>When discussing SRE, I love to pose the question, &#8220;What does it mean to <em>engineer reliability</em>?&#8221;. That&#8217;s what this article is all about.</p>

<div class="sreweekly-description">
<blockquote><p>Blameless recently had the privilege of hosting SRE leaders Craig Sebenik, David Blank-Edelman, and Kurt Andersen to discuss how can SREs approach work as done vs work as imagined, how to define SRE and DevOps and the complementary nature of the two, the ethics of purchasing packaged versions of open source software, and more.</p></blockquote>

<div class="sreweekly-description">
<blockquote><p>Whenever an agent is under pressure to simultaneously act quickly and carefully, they are faced with a double-bind. If they proceed quickly and something goes wrong, they will be faulted for not being careful enough. If they proceed carefully and something goes wrong, they will be faulted for not moving quickly enough.</p></blockquote>

<div class="sreweekly-description">
<p>If your frontend has a hard dependency on multiple microservices, their failure rates are compounded. This article fills in the math behind the paper <a href="https://www2.cs.duke.edu/courses/cps296.4/fall13/838-CloudPapers/dean_longtail.pdf">The Tail at Scale</a> and shows that your backends&#8217; SLOs may have to be significantly tighter than the frontend&#8217;s.</p>
