How can one create an alarm that would notify people of health events in AWS?

1. Using SNS alone

2. Using CloudWatch Events

3. Using CloudWatch Event for AWS Health Events, and SNS for notifications

4. Setting alarms in CloudTrail

The correct answer is: Using CloudWatch Event for AWS Health Events, and SNS for notifications

Creating an alarm to notify people of health events in AWS involves integrating multiple services to ensure both the detection of events and the delivery of notifications. The correct approach is to use CloudWatch Events for monitoring AWS Health Events in conjunction with Simple Notification Service (SNS) for delivering notifications. AWS Health provides information about the performance and availability of AWS services, and this information can be detected through AWS CloudWatch Events. When a health event occurs, a CloudWatch Event can trigger based on predefined rules indicating specific changes or issues. This is essential as it allows the system to monitor for specific health-related events automatically. Once an event is detected, SNS serves as an effective mechanism to send notifications to the desired recipients, whether they are individuals, applications, or systems. By integrating SNS with CloudWatch Events, you can create a more robust notification system whereby users receive timely updates regarding health events affecting their AWS resources. In contrast, using SNS alone lacks the capability to detect AWS Health Events, as SNS is primarily a notification service and does not monitor for event changes by itself. CloudWatch Events plays a crucial role here, making that integration necessary. While CloudTrail is useful for monitoring API calls and actions made in your AWS account, it does not specifically monitor health-related events and
