Ansible vs. Ansible Tower (Automation Controller) Explained

Ansible is an open-source automation tool that uses YAML playbooks for configuration management and deployment, while Ansible Tower (now Automation Controller) adds enterprise features like a web UI, role-based access control, job scheduling, and centralized logging. The key differences include interface (CLI vs web GUI), security features, workflow management, and scalability options. Ansible is free and suitable for smaller teams, while Tower requires a commercial license but provides better collaboration, auditing, and enterprise-grade features for large-scale automation environments.
