Hello,

You may look at fabric: http://www.fabfile.org/
This a great software for running a bunch of commands on a lot of servers.

In order to running a command on a bunch of servers this will look like the following:
fab -R role cmd

cmd is defined in the fabfile.py:
def cmd():
    run('cat /etc/hosts')
