0. Introduction: Why You Need “Tools” Instead of “Common Commands” Abstract: Infrastructure as Code (Terraform) and Configuration Management/Orchestration (Ansible) transform “human repetitive labor” into reproducible code. However, when automation encounters the real world—state drift, hardware, emergency changes, approvals, sensitive information, and third-party dependencies—”boundaries” are exposed. This article explains these gaps, common pitfalls, and practical models … Read more
