Azure Cloud Foundation landing zone architecture organizes enterprise subscriptions across governance, identity, network, and workload tiers using management groups and Azure Policy. Traffic flows from internet users through Azure Front Door and WAF to spoke landing zones (Corp, Online, Data, Sandbox), while on-premises connectivity arrives via ExpressRoute through a hub network with Azure Firewall and Bastion. Identity and access are centralized via Azure Active Directory and Key Vault, with monitoring and compliance enforced through Azure Monitor, Log Analytics, and Microsoft Sentinel across all layers. Fork this diagram to customize management group hierarchies, add additional landing zones, or adjust firewall rules for your organization's security posture. This pattern implements Microsoft's Cloud Adoption Framework best practices for scalable, secure, and compliant Azure deployments.
