Your company hosts an e-commerce web application in the cloud. After a recent marketing campaign, the application experienced intermittent slow response times, causing complaints from users. You are asked to improve the monitoring setup to prevent future performance degradation. Which monitoring strategy should be implemented?
Configure an alert to trigger at 95% CPU usage, assuming this is the threshold where performance issues begin.
Implement monitoring of the number of concurrent users to anticipate when to scale up resources.
Establish baseline performance monitoring with alerts for deviations that could indicate the beginning of performance degradation.
Monitor the performance intensively only during anticipated peak hours to optimize resource use.
