What key advantage does using AWS CloudTrail provide for monitoring?

Using AWS CloudTrail provides a significant advantage in logging API calls, which is essential for auditing and compliance purposes. CloudTrail records all API requests made within your AWS account, capturing detailed information such as who made the request, the services involved, the action taken, and the time of the request. This comprehensive logging capability allows organizations to maintain a clear audit trail of user activity, which is crucial for compliance with regulatory standards and internal policies.

By having this information readily available, organizations can monitor access and changes to their resources, investigate aberrant behavior, and ensure that they adhere to security best practices. This level of visibility is critical for maintaining security and governance within cloud environments.
