What is Ansible?

Ansible is an open-source automation tool used for configuration management, application deployment, orchestration, and task automation. It uses a simple, human-readable language (YAML) to define automation tasks, called playbooks. Ansible connects to managed nodes via SSH or other remote protocols and pushes small programs called modules to them. These modules are then executed, and Ansible removes them when finished. It is commonly used to automate repetitive tasks, deploy applications, configure systems, and orchestrate complex workflows across multiple servers or devices.
