Ansible
=======

Ansible is a radically simple deployment, configuration, and command execution framework.
Other tools in this space have been too complicated for too long, require too much bootstrapping, 
and have too much learning curve.  Ansible is dead simple and painless to extend.  For comparison, Puppet and Chef have about 60k lines of code.  Ansible's core is a little over 1000 lines.  

Ansible isn't just for configuration -- it's also great for Ad-Hoc tasks, 
quickly firing off commands against nodes.  Where Ansible excels though, is expressing complex multi-node deployment processes, executing complex sequences of commands on different hosts through the "playbooks" feature.

Ansible does not require programming in any particular language -- you can write modules
as scripts or programs that return simple JSON.

Why use Ansible versus something else?  (Puppet, Chef, Fabric, Capistrano,
mCollective, Func, SaltStack, etc?) It will have far less code, it
will be more correct, and it will be the easiest thing to hack on and
use you'll ever see -- regardless of your favorite language of choice.
Systems management doesn't have to be complicated.  Ansible's docs will remain 
short & simple, and the source will be blindingly obvious.


Design Goals
````````````

* Dead simple setup
* Super fast & parallel by default
* No server or client daemons; use existing SSHd out of the box
* No additional software required on client boxes
* Modules can be written in ANY language
* Awesome API for creating very powerful distributed scripts
* Be usable as non-root
* Create the easiest config management system to use, ever.
