Ansible works on ‘agentless architecture’. It works by connecting to your nodes and pushes out Ansible modules to them which are small programmes. These modules are written to the resource nodes of the desired state of the system. With the help of SSH, Ansible then executes these modules and removes them when done. Since ansibles are based on agentless architecture, your pool of modules can dwell on any machine without requiring any server, daemons or databases. You just require terminal program, text editor and a version control system to keep a check on changes to your content. Ansible’s “authorized_key” is used to give directions as to what machines will use which hosts.
