Complete Azure landing zone architecture with hierarchical management groups spanning Tenant Root Group through Platform and Landing Zones, enforcing Azure Security Benchmark policies across all tiers. Management groups organize Security, Management, Identity, and Connectivity platforms, while Landing Zones branch into Corp, Online, and Local subscriptions, each with dedicated subnets and a Hub Virtual Network (10.0.0.0/16) secured by Azure Firewall. Policy Initiative: Azure Security Benchmark applies uniformly to Platform and Landing Zones, ensuring compliance and governance at scale.
