 A private cluster is a network of Bacalhau nodes completely isolated from any public node.
 That means you can safely process private jobs and data on your cloud or on-premise hosts!

+Good news: spinning up a private cluster is really a piece of cake :cake::
 
 1. Install Bacalhau `curl -sL https://get.bacalhau.org/install.sh | bash` on every host
 1. Run `bacalhau serve` only on one host, this will be our "bootstrap" machine
