AWS Terraform Application Load Balancer Project

This project provisions a highly available web application infrastructure on AWS using Terraform.
It creates a custom VPC, public subnets across multiple Availability Zones, EC2 web servers, an Application Load Balancer (ALB), and supporting networking resources.

The infrastructure is fully automated and reproducible using Infrastructure as Code (IaC).
