🌐 Multi-Environment Azure Infrastructure Setup

---

📌 Overview

Enterprise-grade 3-Tier Azure Infrastructure built using Terraform and Azure DevOps.

This project demonstrates how to provision and manage Development, Staging, and Production environments using reusable Terraform modules and automated CI/CD workflows.

Key Objectives

• Multi-Environment Infrastructure
• Infrastructure as Code (IaC)
• Secure Networking
• Automated Deployments
• High Availability Architecture
• Enterprise Cloud Governance
