Terraform Infrastructure Automation

🔗 Live App: (Previously deployed — see infrastructure screenshots below)

Provisioned a complete AWS environment using Terraform, including VPC networking, routing, security groups, and EC2 compute, and deployed a publicly accessible web server.

---

Overview

This project demonstrates Infrastructure as Code (IaC) by automating the creation of a complete AWS environment using Terraform.

The system provisions a fully functional cloud architecture and deploys a web server accessible from the internet.

Architecture

Internet ↓ Internet Gateway ↓ Route Table (0.0.0.0/0 → IGW) ↓ Public Subnet ↓ EC2 Instance (Apache Web Server)

⚙️ Tech Stack

• Terraform
• AWS (VPC, EC2, Networking)
• Amazon Linux 2
• Apache (httpd)

---

Features

• Automated VPC creation with DNS support
• Public subnet with internet access
• Internet Gateway and routing configuration
• Security group with SSH (22) and HTTP (80) access
• EC2 instance deployment using Terraform
• Web server installation and configuration
• Terraform outputs for public IP and DNS
• Fully reproducible infrastructure using Terraform

---

Outputs

After running terraform apply, Terraform provides:

• EC2 Public IP
• EC2 Public DNS

Example:

ec2_public_ip  = "44.199.208.243"
ec2_public_dns = "ec2-44-199-208-243.compute-1.amazonaws.com"

---

🌐 Accessing the Application

1. SSH into the instance

ssh -i ~/.ssh/ec2-practice-key.pem ec2-user@<EC2_PUBLIC_IP>

2. Open in browser

http://<EC2_PUBLIC_IP>

Expected Output

Hello from Zonique Terraform project

Key Concepts Demonstrated

• Infrastructure as Code (IaC)
• Terraform state management
• Resource dependencies
• AWS networking (VPC, subnets, routing)
• Security group configuration
• EC2 provisioning and access
• Output variables for automation

---

Project Goal

This project demonstrates building and managing cloud infrastructure using Terraform, transitioning from manual AWS configuration to scalable, repeatable infrastructure deployment.

---

Future Improvements

• Add variables (variables.tf) for reusable configuration
• Use Terraform modules for better structure
• Add user_data to automate web server setup
• Deploy a multi-tier architecture (ALB + multiple EC2s)
