To connect, add your private key and SSH into any client or server with
`ssh ubuntu@PUBLIC_IP`. You can test the integrity of the cluster by running:

  $ consul members
  $ nomad server-members
  $ nomad node-status

If you see an error message like the following when running any of the above
commands, it usuallly indicates that the configuration script has not finished
executing:

"Error querying servers: Get http://127.0.0.1:4646/v1/agent/members: dial tcp
127.0.0.1:4646: getsockopt: connection refused"

Simply wait a few seconds and rerun the command if this occurs.

The Nomad UI can be accessed at http://PUBLIC_IP:4646/ui.
The Consul UI can be accessed at http://PUBLIC_IP:8500/ui.
