Modular Terraform-based Azure infrastructure deployment using best IaC practices.

☁️ Azure Infrastructure Deployment using Terraform Modules

Welcome to this Terraform project where we deploy a complete Azure infrastructure using a modular and reusable approach. This project is ideal for learning, production, or scaling large Azure environments efficiently.

📚 What This Repository Contains

This repository provisions the following Azure resources using Terraform:

• ✅ Resource Group
• 🌐 Virtual Network & Subnets
• 🔐 Key Vault & Secrets
• 🧠 SQL Server & Database
• 💻 Virtual Machines (Linux)
• 🌐 Public IP Address
• 🔌 Network Interfaces
• 🛡️ Network Security Groups

All of these are defined using individual Terraform modules to promote reusability, scalability, and clean structure.

🚀 Getting Started

1. Prerequisites

• Azure CLI installed (az login to authenticate)
• Terraform installed
• A valid Azure subscription

2. Clone the Repository

git clone https://github.com/Riteshatri/modular-infra-azure-terraform.git
cd modular-infra-azure-terraform

3. Initialize Terraform

terraform init

4. Review the Plan

terraform plan -var-file="riteshcustom.tfvars"

5. Apply the Changes

terraform apply -var-file="riteshcustom.tfvars" -auto-approve

✅ Resources will now be deployed to Azure.

---

🔍 Inspect Terraform State

• List all resources:

terraform state list

• Inspect a specific resource:

terraform state show <resource_name>

---

📌 Why Modular Structure?

• ♻️ Reusability: Each module can be reused in other projects.
• 🔍 Separation of Concerns: Easy to debug and scale.
• 🧪 Test Individually: Each module can be tested independently.

---

📥 Variables Management

• variables.tf: All declared variables
• terraform.tfvars: Default values
• riteshcustom.tfvars: Custom values for your environment

To use custom values:

terraform apply -var-file="riteshcustom.tfvars"
