A company is planning a migration from an on-premises data center to the AWS cloud.

The most operationally efficient solution for turning on AWS CloudTrail across multiple AWS accounts managed within an AWS Organization is to create a single CloudTrail trail in the organization ' s management account and configure it to log events for all accounts within the organization. This approach leverages CloudTrail ' s ability to consolidate logs from all accounts in an organization, thereby simplifying management, reducing overhead, and ensuring consistent logging across accounts. This method eliminates the need for manual intervention in each account, making it an operationally efficient choice for organizations planning to scale their AWS usage.
