Ansible

• Orchestration / CfgMgmt / Remote Execution Tool

• Python based uses SSH, WinRM, or API

• Server based, agentless1

• host information in flat files, CMDB, scripts, . . .

• executes the task on the host side

• Playbook : combination of tasks with meta information

• Roles : abstract playbook with tasks, variables and handlers

• Templates : Jinja2

• works where Python works2

1Abstraction of SSH / WinRM to connect with the node and in certain setup an agent might be required, but by default it is

not necessary2

Ansible can actually run without Python on the remote host, however it is not fully supported
