Chapter 4. Installing a three-node cluster on Nutanix
In OpenShift Container Platform version 4.14, you can install a three-node cluster on Nutanix. A three-node cluster consists of three control plane machines, which also act as compute machines. This type of cluster provides a smaller, more resource efficient cluster, for cluster administrators and developers to use for testing, development, and production.

Because application workloads run from control plane nodes, additional subscriptions are required, as the control plane nodes are considered to be compute nodes.
