aws-patterns

AWS production patterns: ECS Fargate with Terraform, VPC 3-tier architecture, IAM least privilege with OIDC (no long-lived credentials), ALB + target groups, RDS Multi-AZ, ElastiCache cluster, S3 lifecycle policies, CloudWatch alarms, Secrets Manager rotation. Use when designing AWS architecture, writing Terraform for AWS, reviewing IAM policies.

Core Principles

VPC 3-tier: public/private/data — load balancers in public, app in private, databases in data subnet; no DB in public

IAM least privilege — no wildcard * resources in production policies; scope to specific ARNs

No long-lived credentials — use IAM roles for EC2/ECS/Lambda; OIDC for GitHub Actions

Multi-AZ everything — RDS Multi-AZ, ElastiCache replication group, ALB spans 3 AZs

Secrets Manager over Parameter Store for secrets — automatic rotation, versioning, cross-account access
