What principle aims to prevent performance issues before they arise in an application?

Proactive monitoring
Performance testing
Reactive analysis
Staged deployments

The correct answer is: Proactive monitoring

Proactive monitoring is focused on identifying and mitigating potential performance issues before they affect the application or its users. This approach emphasizes the use of tools and strategies that continuously observe the application’s performance metrics, user behavior, and system health to anticipate problems. By monitoring in real-time and setting up alerts for specific thresholds, teams can resolve issues before they escalate into actual performance degradation or outages. This principle contrasts with performance testing, which typically occurs during development or before deployment to identify performance bottlenecks. It is more of a review process rather than a continuous monitoring solution aimed at preemptively addressing potential issues. Reactive analysis, on the other hand, deals with problems after they've occurred, analyzing the situation to understand the causes and mitigate future occurrences, rather than preventing problems in the first place. Staged deployments involve gradually rolling out changes to a subset of users to minimize risk, but they do not inherently focus on performance issues before they arise. In this context, proactive monitoring stands out as the best approach for anticipating and addressing performance challenges.
