AWS introduced cross-account delivery for Data Exports, enabling FinOps teams to send Standard exports such as Cost and Usage Reports and Carbon Emissions reports directly into Amazon S3 buckets owned by other AWS accounts. This reduces the need for data replication and duplicate storage across accounts.
Security is maintained by requiring explicit authorization via S3 bucket policies from destination account owners, facilitating centralized analytics and cost management workflows. This feature improves operational efficiency and follows security best practices by separating workloads from management accounts. It's available in all commercial AWS Regions except GovCloud and China regions.
