<p>DevOps keeps evolving but alerting tools are stuck in the past. Any modern alerting tool should be built on these four principles: cost-efficiency, service catalog empowerment, easier scheduling and substitutions, and clear distinctions between incidents and alerts.<br>

<p>To protect your application against failures, you first need to know what can go wrong. [&#8230;] the most common failures you will encounter are caused by single points of failure, the network being unreliable, slow processes, and unexpected load.</p>
