Terraform state management is critical for enterprise teams running infrastructure at scale. Local state is unsuitable for production due to lack of collaboration, no locking, and security risks. Best practices covered include using remote backends (S3, Azure Storage, GCS, Terraform Cloud), enabling state locking with DynamoDB, separating state per environment, encrypting state files, enabling versioning for rollback, modularizing infrastructure to keep state files small, implementing RBAC, and running Terraform through CI/CD pipelines rather than developer machines. A checklist and common mistakes section round out the guidance.
