The vCenter Server design includes both the design for the vCenter Server instance and the VMware Platform Services Controller instance.

A Platform Services Controller groups a set of infrastructure services including vCenter Single Sign-On, License service, Lookup Service, and VMware Certificate Authority (VMCA). You can deploy the Platform Services Controller and the associated vCenter Server system on the same virtual machine(vCenter Server with an embedded Platform Services Controller) or on different virtual machines (vCenter Server with an external Platform Services Controller).
