Discuss Terraform, Infrastructure as Code, and AWS Experience

Discuss your experience with infrastructure as code, Terraform, and AWS. Explain a concrete infrastructure change you worked on, how it was reviewed and applied, and how you handled configuration state and failures. ### Constraints Use only experience you actually have. If you have not used a named tool, explain the closest relevant experience and the gap. Any example architecture must be labeled hypothetical. No specific AWS service or Terraform backend is prescribed. ### Clarifying Questions - Should the example focus on provisioning, repeatable environments, deployment integration, or operations? - Which parts of the infrastructure lifecycle did you personally own? ```hint Explain the state boundary Configuration, recorded management state, and resources actually running in the cloud can disagree. Describe how you detect and resolve that difference. ``` ### What a Strong Answer Covers - Accurate experience and the purpose of declarative infrastructure configuration. - Change review, state management, access boundaries, and handling of drift or partial failure. - Reproducibility, validation, and lessons tied to a real example. ### Follow-up Questions - How would you prevent two operators from applying conflicting changes concurrently? - What would you do if a proposed plan includes an unexpected resource replacement?
