Question

An ecommerce company hosts a web application on Amazon EC2 instances that are in an Auto Scaling group. The company deploys the application across multiple Availability Zones. Application users are reporting intermittent performance issues with the application. The company enables basic Amazon CloudWatch monitoring for the EC2 instances. The company identifies and implements a fix for the performance issues. After resolving the issues, the company wants to implement a monitoring solution that will quickly alert the company about future performance issues. Which solution will meet this requirement?

Accepted Answer

Correct answer: A. Enable detailed (1-minute) monitoring on the EC2 instances, publish custom CloudWatch metrics for application-specific performance indicators, and create CloudWatch alarms on those metrics so the company is alerted quickly. CloudWatch Logs Insights adds log analysis for error patterns. The other options focus on tracing, delivery, or network flow logs rather than fast performance alerting.
