Cloud-Ready .NET Microservices Application

This project demonstrates the development, containerization, and cloud deployment of a .NET 9 microservices-based application using Azure and Kubernetes.

🔧 Technologies

• .NET 9 – Microservices architecture (API, MVC, Workers)
• Docker – Containerization of services
• Azure DevOps – CI/CD pipelines
• AKS (Azure Kubernetes Service) – Orchestration platform
• KEDA – Autoscaling based on external triggers
• Azure Key Vault – Secure secret management
• CosmosDB – Scalable NoSQL database
• Azure Event Hub / Service Bus – Event-driven architecture
• Azure Container Registry (ACR) – Secure Docker image hosting
• Azure Monitor – Monitoring and logging
• Azure App Configuration – Centralized config management

🧩 Architecture Overview

The application consists of:

• An API Gateway for external access
• A MVC Frontend for user interaction
• Several Worker services for background processing
• All services communicate via HTTP and asynchronous messages (Event Hub / Service Bus)

Each component is containerized and deployed to AKS. KEDA dynamically scales the workers based on event volume.

🚀 CI/CD Workflow

Using Azure DevOps Pipelines:

1. Build Docker images for each microservice
2. Push images to Azure Container Registry (ACR)
3. Deploy to AKS using Kubernetes manifests and Helm charts
4. Apply autoscaling policies with KEDA

🔐 Security

• Secrets (DB strings, API keys) are stored and retrieved securely from Azure Key Vault
• Configuration settings are centralized using Azure App Configuration

📈 Monitoring & Testing

• Logs and metrics collected via Azure Monitor
• Load testing conducted using tools like Apache JMeter or k6 to validate scaling performance
