About This Architecture

AWS multi-account model using Organizations centralizes governance across Security/Logging, Production, Development/Pipeline, and Shared Services accounts. AWS Organizations routes policy enforcement, CloudTrail audit logs flow to the Security account, Control Tower manages identity via SSO, while EC2, RDS, and ELB run production workloads isolated from development pipelines using CodePipeline and CodeBuild. This architecture enforces separation of duties, blast radius containment, and cost allocation boundaries—critical for enterprises managing compliance and scaling infrastructure safely.

How should I structure multiple AWS accounts using Organizations for security and compliance?

This diagram shows a four-account model: a central Organizations root manages Security/Logging (CloudTrail, GuardDuty, Security Hub), Production (EC2, RDS, ELB), Development/Pipeline (CodePipeline, CodeBuild), and Shared Services (Control Tower, SSO). This separation enforces least-privilege access, isolates blast radius, and enables per-account cost tracking and audit trails.
