Azure DevOps CI/CD pipeline orchestrating automated builds, tests, and deployments to staging and production VM Scale Sets across segregated subnets. Source code in Azure Repos triggers Azure DevOps Pipelines, which authenticate via Azure AD Service Principal and execute build and test stages on Ubuntu agents, storing artifacts in Azure Artifacts and Key Vault secrets. Quality gates in Azure Monitor validate test results from Application Insights before promoting to staging VMs (Standard_D2s_v3) and production VMs (Standard_D4s_v3) behind Application Gateways. This architecture demonstrates infrastructure-as-code best practices with role-based access control, secrets management, and multi-stage deployment safety. Fork and customize this diagram to match your subscription topology, VM SKUs, and network CIDR blocks. Consider adding Azure Policy for compliance enforcement and Azure Bastion for secure VM access in production environments.
