+The control plane node resource requirements depend on the number and type of nodes and objects in the cluster. The following control plane node size recommendations are based on the results of a control plane density focused testing, or _Cluster-density_. This test creates the following objects across a given number of namespaces:
 
-- 12 image streams
-- 3 build configurations
-- 6 builds
-- 1 deployment with 2 pod replicas mounting two secrets each
-- 2 deployments with 1 pod replica mounting two secrets
-- 3 services pointing to the previous deployments
-- 3 routes pointing to the previous deployments
-- 10 secrets, 2 of which are mounted by the previous deployments
-- 10 config maps, 2 of which are mounted by the previous deployments
+- 1 image stream
+- 1 build
+- 5 deployments, with 2 pod replicas in a `sleep` state, mounting 4 secrets, 4 config maps, and 1 downward API volume each
+- 5 services, each one pointing to the TCP/8080 and TCP/8443 ports of one of the previous deployments
+- 1 route pointing to the first of the previous services
+- 10 secrets containing 2048 random string characters
+- 10 config maps containing 2048 random string characters
