At the same time all of these many customers are responsible <a href="https://docs.aws.amazon.com/imagebuilder/latest/userguide/vulnerability-analysis-and-management.html">to use a recent machine image with current security patches</a>. That means refreshing instances in an Auto Scaling Group is something anybody out there needs to do on a regular basis<sup class="footnote-reference"><a id="footnote-reference-1" href="#footnote-1">1</a></sup> and anybody who does not like busywork will automate the process.</p>
