VPC Setup with Terraform

📌 Project Overview

This project provisions a custom VPC environment on AWS using Terraform. The setup includes subnets, an Internet Gateway, route tables, security groups, and EC2 instances deployed across multiple availability zones. Additionally, an Application Load Balancer (ALB) is configured to distribute traffic between instances.
