AWS Core Infrastructure – Production-Ready Reference Architectures
Explore production-ready AWS core infra with open-source projects: secure 3-tier web apps, resilient deployments, zero-downtime blue/green releases using CDK & Terraform. Includes architecture diagrams, repos, deployment guides, and real-world best practices.
Modern applications need secure, scalable, production-grade infrastructure as a foundation. Our Core Infrastructure reference architectures provide complete blueprints for designing web applications on AWS using best practices, IaC automation, fault-tolerance, and enterprise security.
Every project listed below is open-source, fully documented, and includes architecture diagrams, deployment guides, and cost estimates to help you learn or build faster.

1. enterprise-secure-webapp-3tier
InfraTalesTech Stack: CDK (Go) • VPC • ALB • EC2/ASG • RDS • IAM • WAF
Overview
This architecture represents a full production web app setup with private databases, a public ALB, security groups, a least-privilege IAM design, logging, monitoring, and a backup strategy. Suitable for SaaS, web platforms, and internal enterprise apps.
Architecture Highlights
- 3-tier model: Web → App → DB
- Private subnets for app & DB layers
- WAF-protected public entry
- Autoscaling groups & load balancer
- Centralized logging + CloudWatch metrics
- IAM role separation & secrets manager
Use Cases
- Enterprise Web Applications
- Startups launching scalable SaaS
- Secure migration from on-prem
2. resilient-webapp-3tier
InfraTalesTech Stack: CDK (Java) • Auto Scaling • Multi-AZ
Purpose
Designed for high availability and fault-tolerant production workloads, this architecture ensures traffic continuity even during failures through active health checks and multi-AZ failover.
Key Features
- Multi-AZ resilience
- ASG for self-healing compute
- Blue-green deploy compatible
- Operational dashboards included
3. infratales-zero-downtime-bluegreen-terraform
InfraTales🛠 Tech Stack: Terraform • CodeDeploy • ALB Routing
Goal
Provides an automated Blue/Green deployment pipeline for production without downtime. Perfect for release-safe environments.
Benefits
- Rollback in seconds
- Safe experimentation
- CI/CD integrated pattern
