🏗️ Terraform on AWS — Deploying WordPress via Infrastructure as Code

📘 Overview

This project showcases how to use Terraform to provision and manage AWS infrastructure through an automated, reusable IaC approach. As part of an AWS workshop, the deployment focuses on building a scalable WordPress application integrated with EC2, VPC, IAM, S3, and a MySQL database via RDS. The exercise highlights best practices in cloud architecture, security, and modular configuration using Terraform.

🎯 Objectives

• Master Terraform fundamentals: providers, resources, state files, and variables
• Provision infrastructure via modular configurations
• Create IAM roles and policies following least-privilege principles
• Set up networking layers with VPC, subnets, route tables, NATs, and internet gateways
• Secure EC2 instance traffic using security groups
• Host WordPress static assets in S3
• Configure Amazon RDS for MySQL database hosting
• Generate Terraform outputs for key application components
• Validate successful WordPress deployment
• Inspect and interpret Terraform state files for infrastructure drift and consistency

🔧 Setup & Installation

# Clone the project repository
git clone https://github.com/yourusername/terraform-wordpress.git
cd terraform-wordpress
