Ansible is an open source automation tool for the orchestration, general configuration and administration of computers. When IT insfrastuctures are composed of multiple machines, it becomes time consuming and error prone to keep up with the application deployment, the change of configurations and overall management of them. This inefficient process is solved by Ansible.

Ansible combines software distribution, provisioning, security and compliance, ad-hoc command execution and software configuration management. Network computers are managed, among other things, via SSH and do not require any additional software on the computers to be managed (clientless architecture). Modules use JSON for output and can be written in any programming language. Ansible uses YAML files in the form of Playbooks to formulate reusable descriptions of systems.
