+## Tagging Amazon Resources
+
+Any resources used in a Kubernetes cluster with the Amazon cloud provider must be tagged with a cluster ID.
+
+[Amazon Documentation: Tagging Your Amazon EC2 Resources](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html)
+
+The following resources need to tagged with a `ClusterID`:
+
+- **Nodes**: All hosts added in Rancher.
+- **Subnet**: The subnet used for your cluster
+- **Security Group**: The security group used for your cluster.
+
+	>**Note:** Do not tag multiple security groups. Tagging multiple groups generates an error when creating Elastic Load Balancer.
+
+The tag that should be used is:
+
+```
+Key=kubernetes.io/cluster/<CLUSTERID>, Value=owned
+```
+
+`<CLUSTERID>` can be any string you choose. However, the same string must be used on every resource you tag. Setting the tag value to `owned` informs the cluster that all resources tagged with the `<CLUSTERID>` are owned and managed by this cluster.
+
+If you share resources between clusters, you can change the tag to:
+
+```
+Key=kubernetes.io/cluster/CLUSTERID, Value=shared
+```
