ERRAFORM PRODUCTION LAB (SENIOR LEVEL)

🎯 Objective Build production-grade Terraform infrastructure with: Remote state (S3 + DynamoDB) Secure S3 bucket (encryption, versioning, blocking public access) DynamoDB locking ECR (container registry) Secrets management (SSM + Secrets Manager) Proper security practices 🔷 PART 1 — WHY THIS MATTERS (INTERVIEW ANSWER) ❓ Why S3 + DynamoDB? Answer (short, interview-ready): S3 → stores Terraform state centrally DynamoDB → prevents concurrent runs (locking) Prevents corruption and race conditions Enables team collaboration ❓ Why ECR? Store Docker images securely Integrate with ECS/EKS IAM-controlled access Avoid public registries (security risk) ❓ Why Secrets Management? ❌ BAD: password = "admin123" ✅ GOOD: AWS SSM Parameter Store AWS Secrets Manager Avoid storing secrets in: Terraform code GitHub state file (important!) 🔷 PART 2 — PROJECT STRUCTURE (PRODUCTION) terraform-prod/ │ ├── backend/ │ └── main.tf # S3 + DynamoDB (bootstrap) │ ├── modules/ │ ├── s3/ │ ├── dynamodb/ │ ├── ecr/ │ └──
