Graviton Reference System stores your IT departments domain knowledge into a single configuration point for servers and desktops running Linux. It allows you to keep your computer systems synchronized, clean, and up-to-date, and makes it incredibly easy to recover a system or an entire enterprise of systems in case of disaster. Instead of deploying a single image to your systems, it allows hosts to be subscribed to the applications and packages they actually need. Global changes can be made in one place.
Ansible is a radically simple deployment, configuration, and command execution framework. It is dead simple and painless to extend. Extending Ansible does not require programming in any particular language; you can write modules as scripts or programs which return simple JSON. It’s also trivially easy to just execute useful shell commands.
