Enterprise GCP folder structure organizing Pfizer.com infrastructure across top-level domains (AI-ML, HPC, Foundation), environment tiers (Production, Non-Production, QA, Dev, Sandbox), and regional subdivisions (NA, EU, APAC) with compliance overlays (GxP, GDPR, HIPAA). Data flows from the organization root through SCF-Root into specialized folders, each containing projects like prj-pfe-security-core, prj-pfe-vpc-sc-admin, and prj-pfe-logging-central. This hierarchical design enforces least-privilege IAM policies, isolates blast radius by environment and region, and simplifies cost allocation and compliance auditing across regulated workloads. Fork this diagram to customize folder naming, add new regional branches, or adjust environment tiers for your organization's governance model. The Foundation folder anchors shared services (networking hubs, DNS, logging, billing export) that all downstream projects depend on.
