4)Be a Man Challenge Additional (For Stronger Students)

 “Base lab = Medium. Apply 1–3 multipliers to reach Hard/Expert.”

Global Multipliers
  Multi-account:
    Separate “dev” and “prod” AWS accounts; deploy via Terraform workspaces or different state backends.
  Multi-region:
    Aurora Global DB, cross-region SNS, cross-region EventBridge routing.
  Security:
    IAM least privilege policies (no *:*).
    WAF on API Gateway with basic rules.
    Parameter Store / Secrets Manager, no DB creds in plaintext.
  Observability:
    Structured logging (JSON).
    CloudWatch dashboards for latency, throttles, errors, DLQ counts.
  CI/CD:
    GitHub Actions or CodePipeline running terraform fmt, terraform validate, pytest and deploy.

Per-Lab Examples
   Lab 1: add Rekognition + object labeling + per-user quota checks.
   Lab 2: add idempotency keys for orders + charge simulation + refunds queue.
   Lab 3: add inventory versioning + audit trail table.
   Lab 4: add chaotic event injection and DLQ replay script.
   Lab 5: add semantic caching layer in DynamoDB; add SQL query cost controls.
   Lab 9: capture TPS and Lambda concurrency in Aurora + QuickSight graphs.
   Lab 10: run actual failover drill and log RTO/RPO metrics.
