AWS Well-Architected Templates

Production-ready CloudFormation and CDK templates implementing all five pillars of the AWS Well-Architected Framework.

Built by Cloud Architecture Pro — premium reference architectures for senior cloud engineers.

Overview

This product provides a comprehensive, deploy-ready infrastructure template set that embodies AWS Well-Architected best practices across every pillar. Instead of reading the 300+ page framework document and translating recommendations into IaC yourself, start with these battle-tested templates and customize them for your workload.

Each template is extensively commented with references to the specific Well-Architected pillar, design principle, and best practice it implements, so your team understands the why behind every resource.

What's Included

CloudFormation Templates (6 templates)

Template	Pillar(s)	Description
`cloudformation/vpc-network.yaml`	Reliability, Security	Multi-AZ VPC with public/private/isolated subnets, NAT gateways, flow logs, and network ACLs
`cloudformation/security-baseline.yaml`	Security	IAM roles, KMS keys, Config rules, GuardDuty, Security Hub, and CloudTrail configuration
`cloudformation/high-availability-app.yaml`	Reliability, Performance	Auto Scaling group, ALB, health checks, cross-AZ deployment, and automated recovery
`cloudformation/cost-optimized-compute.yaml`	Cost Optimization	Spot/On-Demand mixed fleet, Savings Plans tagging, auto-scaling schedules, and right-sizing alerts
`cloudformation/performance-monitoring.yaml`	Performance Efficiency, Ops Excellence	CloudWatch dashboards, custom metrics, alarms, and X-Ray tracing configuration
`cloudformation/operational-excellence.yaml`	Operational Excellence	SSM documents, automated patching, runbook automation, and change management

CDK Stacks (Python, 3 files)

File	Description
`cdk/well_architected_app.py`	CDK app entry point composing all stacks
`cdk/networking_stack.py`	VPC, subnets, and connectivity as CDK constructs
`cdk/security_stack.py`	Security baseline as reusable CDK constructs

Documentation

`docs/deployment-guide.md`	Step-by-step deployment instructions for each template
`docs/security-considerations.md`	Security hardening guide and compliance mapping
`docs/cost-optimization-guide.md`	Cost analysis, optimization strategies, and estimator usage
`docs/runbook.md`	Operational runbook for day-2 operations

Scripts & Examples

File	Description
`scripts/pillar_assessment.py`	Interactive Well-Architected review checklist scorer
`scripts/cost_estimator.py`	Estimate monthly costs for a deployment configuration
`examples/params-production.json`	Production-grade parameter set

`examples/params-staging.json`	Staging environment parameter set

Prerequisites

AWS CLI v2 configured with appropriate credentials
An AWS account with permissions to create VPCs, IAM roles, KMS keys, and CloudWatch resources
For CDK: Python 3.10+, Node.js 18+, AWS CDK CLI v2 (npm install -g aws-cdk)

... continues with setup instructions, usage examples, and more.

cdk/networking_stack.py """ Well-Architected Networking Stack — CDK Implementation Creates a production-grade VPC with the same architecture as the CloudFormation vpc-network.yaml template, but using CDK's higher-level constructs for easier customization and composition. Key differences from raw CloudFormation: - CDK's ec2.Vpc construct handles subnet CIDR allocation automatically - VPC endpoints are added as method calls, not separate resources - Flow logs are configured as a property, not a separate stack of resources - Cross-stack references are handled via Python object properties, not exports Implements: Reliability Pillar (REL-02, REL-04), Security Pillar (SEC-05) Author: Cloud Architecture Pro License: MIT """ from constructs import Construct import aws_cdk as cdk import aws_cdk.aws_ec2 as ec2 import aws_cdk.aws_logs as logs class WellArchitectedNetworkingStack(cdk.Stack): """VPC networking stack following Well-Architected best practices.
