 Installing a single-node cluster on {ibmzProductName} and {linuxoneProductName} requires user-provisioned installation using either the "Installing a cluster with {op-system-base} KVM on {ibmzProductName} and {linuxoneProductName}" or the "Installing a cluster with z/VM on {ibmzProductName} and {linuxoneProductName}" procedure.

+= Additional requirements for installing {sno} on a cloud provider
+
+The documentation for installer-provisioned installation on cloud providers is based on a high availability cluster consisting of three control plane nodes. When referring to the documentation, consider the differences between the requirements for a {sno} cluster and a high availability cluster.
+
+* A high availability cluster requires a temporary bootstrap machine, three control plane machines, and at least two compute machines. For a {sno} cluster, you need only a temporary bootstrap machine and one cloud instance for the control plane node and no worker nodes.
+
+* The minimum resource requirements for high availability cluster installation include a control plane node with 4 vCPUs and 100GB of storage. For a {sno} cluster, you must have a minimum of 8 vCPU cores and 120GB of storage.
+
+* The `controlPlane.replicas` setting in the `install-config.yaml` file should be set to `1`.
+
+* The `compute.replicas` setting in the `install-config.yaml` file should be set to `0`.
+This makes the control plane node schedulable.
