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.
