That&#x27;s true, but if an app, say, is running on 4 hosts doing <i>some boutique thing</i> for a small unit of 20 traders, then the practical reality is that they might not want Chaos Monkey bringing down 25% of the throughput randomly, and interrupting whatever actual cash money requests are in progress on a host.<p>Itsa lot easier to promote that if it is thousands of servers doing something fairly mundane where, worst-case, it not working means a tiny tiny proportion of your customers have to restart their video stream. So what?<p>But for a small hetereogenous business where what&#x27;s happening has a much higher cash density, the actual practicalities of randomly killing things in production and the <i>risk</i> that represents rather get in the way, even though <i>in theory</i> you should be able to kill anything in production with minimal impact, you are much less inclined to take that risk when the stakes are higher.
