What is Ansible?

Ansible is an open-source automation tool used for configuration management, application deployment, and IT orchestration. It uses a simple, human-readable syntax written in YAML called playbooks, which makes it accessible to both developers and system administrators. One of Ansible’s key strengths is its agentless architecture—it connects to target machines over SSH (or WinRM for Windows) without requiring any additional software installation, making it lightweight and easy to integrate into existing environments.
