Production Solution & Architecture
AWS Config continuous compliance — detects when actual resource state drifts from desired. CloudFormation Drift Detection — compares stack with deployed resources. Terraform plan in CI — terraform plan in a scheduled job shows drift. Set up alerts to notify when drift is detected.

⚡ 60-Second Elevator Pitch Talking Points
- Immediate Triage: AWS Config continuous compliance — detects when actual resource state drifts from desired. Clou
- Run targeted verification commands before modifying configuration.
- Automate permanent guardrails (CI check, alerts, IaC policy) to prevent recurrence.
