 Typhoon has experimental support for ARM64 with Fedora CoreOS on AWS. Full clusters can be created with ARM64 controller and worker nodes. Or worker pools of ARM64 nodes can be attached to an AMD64 cluster to create a hybrid/mixed architecture cluster.

-## AMIs

-In lieu of official Fedora CoreOS ARM64 AMIs, Poseidon publishes experimental ARM64 AMIs to a few regions (us-east-1, us-east-2, us-west-1). These AMIs may be **removed** at any time and will be replaced when Fedora CoreOS publishes equivalents.

+# Nodes
+
+Typhoon clusters consist of controller node(s) and a (default) set of worker nodes.
+
+## Overview
+
+Typhoon nodes use the standard set of Kubernetes node labels.
+
+```yaml
+Labels: kubernetes.io/arch=amd64
+        kubernetes.io/hostname=node-name
+        kubernetes.io/os=linux
+```
+
+Controller node(s) are labeled to allow node selection (for rare components that run on controllers) and tainted to prevent ordinary workloads running on controllers.
+
+```yaml
+Labels: node.kubernetes.io/controller=true
+Taints: node-role.kubernetes.io/controller:NoSchedule
+```
+
+Worker nodes are labeled to allow node selection and untainted. Workloads will schedule on worker nodes by default, baring any contraindications.
+
+```yaml
+Labels: node.kubernetes.io/node=
+Taints: <none>
+```
+
+On auto-scaling cloud platforms, you may add [worker pools](/advanced/worker-pools/) with different groups of nodes with their own labels and taints. On platforms like bare-metal, with heterogeneous machines, you may manage node labels and taints per node.
+
+## Node Labels
+
+Add custom initial worker node labels to default workers or worker pool nodes to allow workloads to select among nodes that differ.

+      machine_type = "n1-standard-16"
+      node_labels  = ["pool=big"]
+    }
+    ```
+
+In the example above, the two default workers would be labeled `pool: default` and the additional worker would be labeled `pool: big`.
+
+## Node Taints
+
+Add custom initial taints on worker pool nodes to indicate a node is unique and should only schedule workloads that explicitly tolerate a given taint key.
+
+!!! warning
+    Since taints prevent workloads scheduling onto a node, you must decide whether `kube-system` DaemonSets (e.g. flannel, Calico, Cilium) should tolerate your custom taint by setting `daemonset_tolerations`. If you don't list your custom taint(s), important components won't run on these nodes.
