🎙️ Candidate Opening & Architectural Context
""Treat Terraform code with the same rigor as application code: pre-merge plans, state locks, and automated drift detection. When addressing this question, I walk the interviewer through our production incident runbook: isolating the blast radius, checking diagnostic logs and metrics, and applying a safe fix.""

1️⃣
Initial Diagnostics & Root Cause Analysis
Use validate in pre-commit hooks (fast, no credentials). Use plan in CI after credentials are available. Both should run before any apply.
terraform validate— checks syntax and basic configuration correctness without connecting to any APIs. Fast. No credentials needed. Checks: valid HCL, valid attribute names, correct argument types.terraform plan— connects to the provider, reads current state, computes what changes would be made. Shows create/update/destroy. Slow (API calls). Needs credentials.
