Automated Three-Tier Architecture on AWS

This Terraform project automates the deployment of a highly available, secure three-tier architecture on AWS.

Key Features:

• Multi-AZ VPC: Public and private subnets across Availability Zones for redundancy.
• Scalable Web Tier: Elastic Load Balancer distributes traffic across web servers in the public subnet and application servers in the private subnet.
• Secure Application Tier: Application servers in a private subnet process business logic, isolated from the internet.
• Managed Database: RDS instance in a private subnet securely stores application data.
• Robust Networking: Route tables and security groups enforce communication policies and network security best practices.
