FizzBuzz as a distributed service, using HashiCorp's Serf.
You'll need Vagrant and Ansible installed to launch the VMs.
$ brew install vagrant
$ brew install ansible
$ vagrant plugin install vagrant-hostmanager
$ vagrant up
You should then be able to ssh into any of the four instances with:
$ vagrant ssh buzz1 # (or fizz1, fizz2 or buzz2)
And running (in the VM), in the vagrant home directory:
./fizzbuzz
