How Do I Prevent Cluster Nodes from Being Exposed to Public Networks?

Question

How do I prevent cluster nodes from being exposed to public networks?

Solution

  • If access to port 22 of a cluster node is not required, you can define a security group rule that disables access to port 22.
  • Do not bind an EIP to a cluster node unless necessary.
