 By default, each cluster creates the following instances:
 
 * One bootstrap machine, which is removed after installation
 * Three control plane machines
 * Three compute machines
 
+ifndef::upi[]
+Because the bootstrap and control plane machines use `Standard_D8s_v3` virtual
+machines, which use 8 vCPUs, and the compute machines use `Standard_D4s_v3`
+virtual machines, which use 4 vCPUs, a default cluster requires 44 vCPUs.
+The bootstrap node VM, which uses 8 vCPUs, is used only during installation.
