This open source IT engine automates application operation and cloud provisioning. It was created in 2012 by AnsibleWorks, and is now owned by Red Hat. Ansible is developed in Python, is lightweight and has fast deployment. As Python is used to build most Linux and UNIX systems, getting Ansible up and running is very quick, and its agentless feature makes it easy to be set up and used. It can also be run from CLI commands without using configuration files such as reboot. For comparatively difficult tasks, its configuration is handled by the YAML syntax in the configuration file known as ‘playbook’. Ansible commands can be written in any programming language and sent over in JSON format. It has also recently started supporting Windows.


This powerful open source system was initially developed by Google for managing containerised applications in a cluster environment. Kubernetes was launched in 2014 after more than a decade of experience of running production workloads at Google with Google’s internal container cluster managers Borg and Omega.
