Ansible is an open-source automation tool, which is categorized into two types of servers :
* Controlling machines
* Nodes
Ansible will be installed on the controlling machine, and using that machine nodes are managed with the help of SSH. Nodes’ locations are specified by inventories in that controlling machine.
Since Ansible is an agentless tool, it doesn’t require any mandatory installations on remote nodes. So, there is no need of background programs to be executed while it is managing any nodes.
Ansible can handle a lot of nodes from a single system over an SSH connection with the help of Ansible Playbooks. Playbooks are capable of performing multiple tasks, and they are in the YAML file format.
