 .Rules for infrastructure node resizing alerts
 
 Resizing alerts are triggered for the infrastructure nodes in a cluster when it has high-sustained CPU or memory utilization. This high-sustained utilization status is:
 
-* Infrastructure nodes sustain over 50% utilization on average in a classic ROSA cluster with a single availability zone using 2 infrastructure nodes.
-* Infrastructure nodes sustain over 66% utilization on average in a classic ROSA cluster with multiple availability zones using 3 infrastructure nodes.
+* Infrastructure nodes sustain over 50% utilization on average in a cluster with a single availability zone using 2 infrastructure nodes.
+* Infrastructure nodes sustain over 66% utilization on average in a cluster with multiple availability zones using 3 infrastructure nodes.
