Terraform Module Structure

📌 Terraform Infrastructure Overview

🗂 Project Structure

Your Terraform project is organized into various modules, each responsible for a specific infrastructure component:

Terraform/
├── modules/
│   ├── vm/                 # Virtual Machine 
│   ├── vmss/               # Virtual Machine Scale Sets
│   ├── Vnet/               # VNet, Subnets, NSGs
│   ├── KV/                 # Key Vault, IAM policies
│   ├── storage/            # Storage accounts, Blob storage
│   ├── db/                 # Databases (PostgreSQL)
│   ├── gateway/            # Azure Gateway setup
├── main.tf                 # Root Terraform configuration
├── data.tf                 # Fetches existing cloud resources (e.g., existing VMs, storage, Device Ip)
├── outputs.tf              # Captures values for use in other modules or external systems
├── provider.tf             # Specifies cloud provider configurations (Azure)
├── terraform.tfvars        # Stores variable values for easy customization
└── variables.tf            # Defines input variables to make configurations flexible

📊 Brainboard Illustration To simplify the logical flow of this infrastructure ⬇

This diagram shows dependencies between key components:

• Resource Groups define logical units.
• Virtual Machines & VMSS provide scalable compute resources.
• Networking & Subnets ensure secure communication across components.
• Storage & Databases handle persistent data storage.
• Azure Gateway & Bastion Host secure remote connections.
• Key Vault protects sensitive information.

🔎 How It Works

Terraform provisions this infrastructure automatically, ensuring:

• Modular Design: Each component is reusable & independent.
• Scalability: VMSS ensures dynamic scaling based on demand.
• Security: NSGs, IAM policies, and Key Vault enhance protection.
• Automation: GitHub Actions & Terraform ensure consistent deployment.
