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.
Extending ansible does not require programming in any particular language -- you can write modules

useful shell commands.
Why use Ansible versus something else? (Puppet, Chef, Fabric, Capistrano,

Systems management doesn't have to be complicated. Ansible's docs will remain
short & simple, and the source will be blindingly obvious.
