AWS Patterns

Status

Master Plan - Comprehensive init.md complete, ready for SKILL.md implementation

Comprehensive AWS architectural patterns covering service selection, Well-Architected Framework, and infrastructure as code across 200+ AWS services.

Scope​

This skill provides decision-first frameworks for AWS service selection, covering:

  • Compute: Lambda vs. Fargate vs. ECS vs. EKS vs. EC2
  • Storage: S3 tiers, EBS, EFS, FSx optimization
  • Databases: RDS vs. Aurora vs. DynamoDB selection
  • Networking: VPC design, load balancing, CloudFront
  • Security: IAM, KMS, Secrets Manager, WAF patterns
  • Cost Optimization: Reserved instances, Savings Plans, Spot instances

Key Components​

  • Service Selection Frameworks - When to use each AWS service
  • Well-Architected Pillars - Operational excellence, security, reliability, performance, cost, sustainability
  • Serverless Patterns - Lambda + API Gateway + EventBridge + DynamoDB
  • Container Patterns - ECS on Fargate, EKS cluster design
  • Multi-IaC Support - CDK, Terraform, and CloudFormation examples
  • 2025 Best Practices - Lambda SnapStart, S3 Express One Zone, Aurora Limitless

Decision Framework​

Compute Service Selection:

Event-driven (<15 min) → Lambda
Stateless containers → Fargate
Need Kubernetes → EKS
Need control plane → EC2

Database Selection:

Relational + MySQL/PostgreSQL → RDS or Aurora
Key-value + scale → DynamoDB
Multi-region ACID → Aurora Global Database

Tool Recommendations​

  • AWS CDK (TypeScript/Python) - Type-safe infrastructure with L2/L3 constructs
  • Terraform (HCL) - Multi-cloud IaC with AWS provider
  • AWS CLI v2 - Command-line management with SSO support
  • boto3 (Python SDK) - Automation and scripting

Integration Points​

  • writing-infrastructure-code - AWS-specific IaC patterns (CDK, CloudFormation)
  • operating-kubernetes - EKS cluster operations and IAM for Service Accounts
  • building-ci-pipelines - AWS CodePipeline, CodeBuild, CodeDeploy
  • secret-management - Secrets Manager and Parameter Store
  • optimizing-costs - AWS Cost Explorer, Budgets, Compute Optimizer
  • implementing-observability - CloudWatch, X-Ray distributed tracing
