What is the main function of AWS CloudTrail?

The main function of AWS CloudTrail is to provide governance and auditing of AWS account activity. CloudTrail records account activity and API usage across your AWS infrastructure, capturing events that allow you to gain insights into your account's operations. It logs every API call made within your account along with details such as who made the call, when it occurred, from where, and the status of the request. This extensive logging enables organizations to run audits, maintain security monitoring, and ensure compliance with various regulations.

With these capabilities, CloudTrail empowers users to understand and trace actions taken on their AWS resources, making it an essential tool for compliance audits and operational troubleshooting. The detailed logs can also be integrated with other AWS services to enhance security and provide deeper analysis, reinforcing its role in governance and auditing.

The other options focus on different functionalities that are not specific to CloudTrail, such as performance monitoring, log data collection, and event-driven workflows, which are managed by other AWS services.
