Azure Enterprise Landscape Overview depicts a three-subscription architecture spanning DEV, TEST, and PROD environments, each with isolated resource groups, VNet integration, Key Vault, Managed Identity, and Container Apps. Developers commit to Repositories via Azure DevOps, triggering CI/CD Pipelines that orchestrate authentication and deployment flows across all three subscriptions with promotion gates. Each environment accesses shared Cross-Cutting Platform Services including Monitoring/Log Analytics, Azure Policy, Cost Management, Azure AD, Sentinel, and Network Security Groups for centralized governance. This multi-subscription pattern isolates blast radius, enforces identity-based access control, and demonstrates Azure best practices for enterprise workload isolation and compliance. Fork this diagram on Diagrams.so to customize resource groups, add application-specific services, or adapt promotion workflows for your organization. The architecture emphasizes least-privilege access through Managed Identity and audit trails via Log Analytics across all tiers.
