How can you monitor your AWS resources to ensure they are performing as expected?

Monitoring AWS resources effectively is crucial for ensuring that they are performing optimally. The chosen answer emphasizes the importance of using Amazon CloudWatch, which is a powerful monitoring service designed specifically for AWS environments.

Amazon CloudWatch allows users to collect and track metrics, collect log files, and set alarms. This helps in assessing the performance of AWS resources such as EC2 instances, RDS databases, and more. By using CloudWatch, you can gain insights into how your applications and services are running, detect anomalies, and respond proactively to any issues that may arise.

Furthermore, performing periodic reviews in conjunction with CloudWatch enables organizations to continuously refine their monitoring strategy. This practice ensures that the monitoring approach evolves alongside the architecture and operational requirements, leading to improved performance and decision-making.

In contrast, relying solely on user feedback does not provide a comprehensive view of system performance, as it may only capture a small, subjective part of the overall operational picture. Using infrastructure as code tools is beneficial for provisioning resources but does not directly relate to monitoring resource performance. While Amazon SNS can be utilized for notifications related to specific events or alarms set within monitoring tools, it does not itself provide the performance metrics and insights necessary for comprehensive monitoring.
