What is Ansible?

Ansible is an open-source automation tool used for configuration management, application deployment, task automation, and orchestration. It allows users to define the desired state of their systems and automate the process of achieving that state across multiple servers or environments. Ansible uses a simple, human-readable language (YAML) to describe automation tasks in the form of playbooks. It operates over SSH and does not require any agent installation on the managed nodes, making it lightweight and easy to use.
