About This Architecture

AWS Landing Zone multi-account architecture with centralized governance through AWS Organizations, Control Tower, and IAM Identity Center managing Security, Log Archive, Shared Services, Development, Test, and Production OUs. Management Account orchestrates organization-wide policies via CloudTrail, AWS Config, CloudFormation StackSets, Firewall Manager, and Security Hub aggregation, while delegated admin accounts enforce compliance and threat detection. Shared Services Account provides Transit Gateway, Direct Connect, Network Firewall, and Route 53 Resolver for network connectivity, with Production Account spanning multi-region Aurora and EC2 deployments across us-east-1 and eu-west-1. This architecture implements AWS best practices for blast radius isolation, centralized logging to S3 and CloudWatch, and automated compliance monitoring—critical for enterprises managing hundreds of workloads across teams.

Consider adding AWS SSO permission sets and cross-account IAM roles to show identity federation patterns.
