Something about View Manager and View Administrator

Hi, All

I refer the following site for new VMware Horizon View 5.2 architecture. I found there is no View Manager in component list.

The following site from VMware Horizon View Administration tells me that we can add vCenter Server Instances to View Manager through View Administrator.

I wonder what View manager is and Is it a sub component or a service of View Connection server? And What is the difference between View Manager and View

Administrator?
