Brief
Ansible no client, dependent on the underlying communication software, based on the Linux system OpenSSH communication, user authentication by the management node invokes various application modules will push instruction is performed by the management terminal Ansible tool automatically deleted after the implementation of temporary files produced.
Ansible course of division of roles:
1, users: Ansible toolset

3, the user directly using Ad-Hoc temporary command set call Ansible tools to accomplish the task execution.
4, the user prewritten Ansible Playbook good pre-programmed set of tasks in order to complete the task execution.
A second portion --Anisble toolset
ansible command is ansible core tools, ansible command not complete all of its own feature set, just call entry Ansible mission, all the commands of the set is completed by a tool, the core tool ansible command:
- INWENTORY: Audience command configuration file
- API: Application Programming Interface provides a third seal program calls
- MODULES: a wealth of built-in module
- PLUGNS: built-in and custom plug-ins
