Red Hat Ansible is a model-driven, configuration management, multi-node deployment/orchestration and remote task execution system. It uses SSH by default, so there is no special software to be installed on the nodes you manage. Ansible is written in Python but can be extended in any language.
Red Hat® Ansible® is a model-driven, configuration management, multi-node deployment/orchestration and remote task execution system. It uses SSH and Python by default, so there is no special software to be installed on the nodes you manage. Simply, it is an agentless configuration management tool. Ansible can be extended in any language, as long as the modules can process and respond with JSON.
The biggest advantage of Ansible over other configuration management technologies is, it is agent-less, i.e., no clients need to be installed, which avoids the chicken and egg problem.
The name "ansible" is taken from the science fiction concept of a machine capable of instantaneous or superluminal communication.
While only a Linux node can be used as a control machine, it remains nonetheless possible to have Windows nodes as a target into Ansible.
Ansible capabilities have gained a lot of modules to cover Infrastructure as a Service, Platform as a Service, and Service as a Service.
Ansible is also capable of interacting with a lot of network equipment like Cisco IOS, Juniper Junos or F5 Bigip.
