Consolidate and query AWS CloudTrail data across accounts and regions using AWS CloudTrail Lake

The blog post provides a walkthrough on how to set up a centralized CloudTrail Lake that consolidates historical CloudTrail event logs with new CloudTrail events, and query the data across accounts and regions.

The first step is to create a multi-account, multi-region event data store in CloudTrail Lake. Then, the blog shows how to import existing CloudTrail logs from an S3 bucket into CloudTrail Lake. Finally, it demonstrates how to query historical and recent data across multiple regions and accounts.

Overall, CloudTrail Lake provides a fully managed, central query mechanism for CloudTrail events across accounts and regions, allowing teams to easily spot trends and gain insights from their data.
