Azure Landing Zone enterprise-scale architecture organizes the Brit Azure Estate across Management Groups, Platform Subscriptions, and Landing Zone Subscriptions with segregated Corp, Online, and Sandbox environments. Identity via Entra ID, connectivity through Virtual WAN and Azure Firewall in UK South, and on-premises integration via ExpressRoute establish secure, compliant network topology. Azure Policy, Defender for Cloud, and Cost Management enforce governance and regulatory compliance (FCA/NCSC standards) across all subscriptions. Fork this diagram to customize your own multi-region landing zone blueprint, adjust firewall rules, or add additional compliance policies for your organization.
