This is particularly beneficial for larger enterprises that utilize multiple AWS accounts to enhance security, manage billing, or segregate workloads. By using Config Aggregators, AWS customers can consolidate and aggregate configuration histories and compliance statuses, making it much easier to perform compliance checks and audits on a broader scale than what would be possible with a single account or region.

AWS Config Rules are used to evaluate the configurations of AWS resources and ensure that they comply with specified policies. While they are essential for governance, they operate within the confines of a single account and do not aggregate data across multiple accounts and regions.

AWS CloudTrail provides logging for API calls across AWS services, recording activity at the account level, but its focus is more on tracking actions performed by users and services rather than aggregating resource configurations.
