Salt is a powerful remote execution manager that can be used to administer servers in a fast and efficient way.
Salt allows you to execute commands simultaneously on all of, or a select number of, machines at once. Salt also allows you to remotely configure these machines using simple to read and write yaml syntax.

salt '*' test.ping
You can install packages, create users, check out git repositories, and a whole lot more with SALT too:
