<p>There&#8217;s a lot you can get out of this one even if you don&#8217;t happen to be using one of the helm charts they evaluated. Their evaluation criteria are useful and easy to apply to other charts &mdash; and also a great study guide for those new to kubernetes.</p>

<p>It&#8217;s interesting to think of money spent on improving reliability as offsetting the cost of responding to incidents. It&#8217;s not one-to-one, but there&#8217;s an argument to be made here.</p>
