Web Application Infrastructure on AWS using Terraform

Web Application Infrastructure on AWS using Terraform

This project builds a multi-tier architecture on AWS to host a simple web application using Terraform. It demonstrates best practices for organizing a cloud environment with public/private subnets, security groups, NAT, Nginx reverse proxy, and Application Load Balancers (ALB).

Key AWS Resources

VPC: With 2 Public and 2 Private Subnets across 2 AZs

Internet Gateway: For Public Subnets

NAT Gateway: For Private Subnets internet access

Route Tables: Public and Private routing properly configured

Security Groups: Secure traffic flow between layers

EC2 Instances:

Public Subnets: Nginx Reverse Proxy Servers

Private Subnets: Flask Web Application Servers (port 5000)

Application Load Balancers:

Public ALB (routes to Nginx)

Internal ALB (routes from Nginx to Backend)

S3 Bucket: Used for storing Terraform remote state
