Multi-Region identity-based access to Amazon Redshift and S3 Tables

This article demonstrates how to set up multi-Region identity-based access to Amazon Redshift and S3 Tables using IAM Identity Center Multi-Region, Lake Formation, and S3 Access Grants for centralized user management across AWS regions.

• Enable IAM Identity Center Multi-Region by creating a multi-Region AWS KMS key and replicating it to additional regions
• Configure Amazon S3 Tables integration with Lake Formation for fine-grained table and column-level access control
• Use Trusted Identity Propagation (TIP) to pass user identity and group memberships through AWS services
• Implement two data access patterns: SELECT queries through Lake Formation and UNLOAD/COPY through S3 Access Grants
• Grant Lake Formation permissions to IAM Identity Center groups for identity-based access without additional IAM role configurations
• Verify access control and authorization through AWS CloudTrail events for both S3 Access Grants and Lake Formation

Organizations can now manage users centrally while enabling consistent identity-based access to analytics workloads across multiple AWS regions without additional user provisioning.
