RunDeck is a command automation hub that helps you automate ad-hoc and routine procedures in data center or cloud environments. It allows you to run tasks on any number of nodes from a Web-based or command-line interface. It also includes other features that make it easy to scale up your scripting efforts, including access control, workflow building, scheduling, logging, and integration with external sources for node and context data.
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.
