Amazon CloudWatch is primarily designed for monitoring AWS resources and applications in real time. This service provides you with critical insights into your AWS environment and applications, allowing you to track metrics such as CPU utilization, disk reads and writes, and network traffic. By continuously monitoring these metrics, CloudWatch enables you to collect and visualize data, set alarms, and automatically react to changes in your AWS environment.

For example, CloudWatch can trigger actions based on specific thresholds, such as scaling up resources when CPU utilization exceeds a certain percentage or notifying administrators when disk space is low. This real-time monitoring capability is essential for ensuring application performance and availability, making it a vital tool in cloud operations.

Other choices focus on functionalities that are not the core function of CloudWatch. User access management is typically handled by AWS Identity and Access Management (IAM). Automating scaling of EC2 instances falls under AWS Auto Scaling, which works in conjunction with CloudWatch but is not its primary function. Creating and managing stacks of resources relates to AWS CloudFormation, another separate service focused on infrastructure as code.
