AWS-VPC-Webserver-Database-AutoScaling

This repository contains the AWS Cloud Foundations Project, designed to demonstrate a complete two-tier architecture involving presentation and data storage layers using various AWS services. This project showcases an auto-scalable web server setup with a load balancer and a database service.

Project Overview

The project is structured to provide a hands-on experience with AWS, focusing on building a scalable and robust web application infrastructure. Below are the main components:

• Presentation Tier: Utilizes Apache web servers running on Linux EC2 instances within an autoscaling group.
• Data Storage Tier: Managed by an RDS cluster featuring a primary and a secondary instance for high availability.
