AWS Python Backend Infrastructure

Infrastructure as Code (IaC) for deploying a Python backend API on AWS with a focus on security, scalability, and cost awareness.

Overview

This repository defines the AWS infrastructure required to run a containerized Python backend in a production-like environment.

The goal is to demonstrate practical cloud architecture, not a fully enterprise-grade setup.

Architecture

The infrastructure includes:

• VPC with public and private subnets
• Application Load Balancer
• ECS-based container execution
• RDS PostgreSQL
• IAM roles with least-privilege access
• Centralized logging

Tech Stack

• AWS
• Terraform
• Docker
• ECS
• RDS PostgreSQL

Key Design Decisions

• ECS over EKS: lower operational complexity
• Private subnets for compute: reduced attack surface
• Terraform modules: separation of concerns and reusability
• Single-region deployment: simplicity and cost control

Cost Considerations

• Right-sized instances
• Minimal NAT usage
• No always-on autoscaling by default

Trade-offs

• Limited high availability (single region)
• No advanced observability stack

Non-Goals

• Kubernetes orchestration
• Multi-cloud support
• Zero-downtime deployments

Possible Extensions

• Blue/green deployments
• Multi-environment support
• Enhanced monitoring
