Beginning in vSphere 7.0, deploying or upgrading vCenter Server in vSphere 7.0 requires the use of vCenter Server appliance, a preconfigured virtual machine optimized for running vCenter Server.
The new vCenter Server contains all Platform Services Controller services, preserving the functionality and workflows, including authentication, certificate management, and licensing. It is no longer necessary nor possible to deploy and use an external Platform Services Controller. All Platform Services Controller services are consolidated into vCenter Server, and deployment and administration are simplified.
As these services are now part of vCenter Server, they are no longer described as a part of Platform Services Controller. In vSphere 7.0, the vSphere Authentication publication replaces the Platform Services Controller Administration publication. The new publication contains complete information about authentication and certificate management.
