Ansible is a free and open-source automation tool that has two types of servers:
- Controlling machines
Ansible will be installed on the controlling machine, and nodes will be controlled through SSH using that machine. The positions of nodes are determined by inventories in the controlling machine.
Ansible does not require any necessary installs on distant nodes because it is an agentless technology. As a result, no background processes are required to be run while it manages any nodes.
With the aid of Ansible Playbooks, Ansible can manage a large number of nodes from a single machine through an SSH connection. Playbooks are multi-tasking scripts that are stored in the YAML file format.
