Ansible (Automation Tool for IT Management)

Ansible is a free configuration management tool, it supports managing the configurations of Unix-like and Microsoft windows systems. Ansible manages nodes over SSH or PowerShell and python to be installed on them.

Ansible is agent-less, that means no need of any agent installation on remote nodes, so it means there are no any background daemons or programs are executing for Ansible, when it’s not managing any nodes.

Ansible can handle 100’s of nodes from a single system over SSH connection and the entire operation can be handled and executed by one single command ‘ansible’. But, in some cases, where you required to execute multiple commands for a deployment, here we can build playbooks.
