Ansible consists of nodes and controlling machine. The controlling machine is the place where Ansibles are installed and nodes are managed by these machines over SSH. With help of SSH protocols, controlling machines deploy modules which are temporarily stored on remote nodes. They will then communicate with the Ansible machine over standard output through JSON connection. Since Ansible is agentless, it controls more than 100 nodes using SSH and the entire operation can be managed using one single command ansible. In cases where you have to build multiple commands, you have to create playbooks in YAML file format. Playbooks are nothing but a bunch of commands which can perform numerous tasks.
