<p>In this blog, we’ll look at three important facts about serverless reliability that teams often overlook. We’ll explain what they are, what the risks are of not addressing them, and how you can make your serverless applications more fault-tolerant.</p>

<li>Serverless architectures don’t guarantee reliability.</li>
<li>You <em>do</em> have control over serverless reliability.</li>
<li>Serverless reliability practices can benefit <em>all</em> platforms, not just serverless platforms.</li>
