DevOps Project: Azure Minimal API + Function with Full CI/CD and Monitoring

Welcome to the Azure DevOps Demo Project!
This project demonstrates a full-featured DevOps pipeline and infrastructure automation using:

• Azure infrastructure provisioning with Terraform
• A .NET 8 Minimal API application
• A serverless Azure Function for custom logging
• CI/CD using both GitHub Actions and Azure DevOps
• Built-in monitoring and alerting using Application Insights and Log Analytics

🚀 Project Structure

/src/Azure-demo-app/                - .NET 8 Minimal API app
/src/Azure-demo-function/          - Azure Function (log ingestion)
/infra/                            - Terraform files (App Plan, Function App, Insights, etc.)
.github/workflows/                 - GitHub pipelines (App + Function)
/azure-pipelines.yml               - Azure DevOps pipeline

---

🛠️ Technologies Used

• Azure App Service + Function App
• Terraform (IaC for clean deployments)
• Azure DevOps Pipelines
• GitHub Actions
• Application Insights + Log Analytics
• C# .NET 8 Minimal API + Azure Functions
• PowerShell & Python scripts (for health checks and alert simulations)

---

🔧 Infrastructure Provisioned

• App Service Plan + Web App (for Minimal API)
• Linux Function App (serverless logging endpoint)
• Azure Storage (Function App dependencies)
• Application Insights + Log Analytics Workspace
• Monitoring setup (availability test, alerts, traces)

---

🖥️ Deploying the App & Infrastructure

Prerequisites:

• Terraform CLI
• Azure CLI
• Azure account with permission to create resources

az login
cd infra/
terraform init
terraform apply

---

🔒 Authentication & Secrets

Authentication is handled using a Service Principal with environment variables:

Variable	Description
ARM_CLIENT_ID	SP App ID
ARM_CLIENT_SECRET	SP Secret
ARM_SUBSCRIPTION_ID	Subscription ID
ARM_TENANT_ID	Tenant ID

These are stored in:

• GitHub → Repository → Secrets
• Azure DevOps → Service Connections

---

⚙️ CI/CD Pipelines

GitHub Actions:

• App: Deploys the Minimal API to App Service
• Function: Deploys the Azure Function via publish profile

Azure DevOps:

• Full pipeline: Terraform infra + build + deploy
• Triggered on commits to devops branch
• Pushes build artifacts and deploys the web app

---

🔍 Monitoring & Automation

• Application Insights: request logs, traces, exceptions
• Log Analytics: custom KQL queries
• Alerts: error thresholds and performance drop detection
• Availability Test: pings /hello endpoint
• Custom scripts:
  • PowerShell: simulate errors, test alert flow
  • Python: monitor health and call logging endpoint

---

📈 Future Additions

• Auto-scaling policy
• Azure Key Vault integration
• Alerting via Teams or Slack
• Container-based deployment to AKS
