Ansible is a powerful, agentless (but easy-to-use and lightweight) automation tool that’s been steadily gaining popularity since its introduction in 2012. This popularity is due in part to its simplicity. Ansible’s most basic dependencies, Python and SSH, are available by default almost everywhere, making it easy to use Ansible for a wide range of systems: servers, workstations, Raspberry Pis, industrial controllers, Linux containers, network devices, and so on.
