Explanation

Monitoring CPU Utilization: The solution needs to detect surges in CPU utilization. Using an Amazon CloudWatch alarm to monitor the average CPU utilization over a short period (5 minutes) is a good approach. A 5- minute period allows for timely detection of surges compared to a longer period (like 15 minutes). Threshold and Metric Statistic: Using the average of the CPU utilization metric helps to smooth out short-term fluctuations and provides a reliable indication of sustained surges. An upper threshold of 80% is used to trigger the alarm when CPU usage consistently remains high. Sending Email Alerts: Amazon Simple Notification Service (Amazon SNS) is the recommended service to send email alerts. By creating an SNS topic and subscribing the development team's email address, the alarm notification can be sent as an email whenever the alarm state is triggered.
