[StarCluster] Local master node

I agree: you can shut that node down while the cluster is running, too.

A t2.nano costs  about 2/3 of a penny per hour. In my opinion it's not worth doing any extra engineering effort to avoid that cost.

The newly brought up instance will now be a coordinator node that can take commands to manage a cluster.
