This service acts as a central administrator for VMware ESXi servers that are connected on a network. vCenter Server provides the central point for configuring, provisioning, and managing virtual machines in the datacenter.
In addition to using these virtual machines as sources for virtual machine desktop pools, you can use virtual machines to host the server components of Horizon 7, including View Connection Server instances, Active Directory servers, Microsoft RDS hosts, and vCenter Server instances.
You can install View Composer on the same server as vCenter Server or on a different server. vCenter Server then manages the assignment of the virtual machines to physical servers and storage and manages the assignment of CPU and memory resources to virtual machines.
You can install vCenter Server either as a VMware virtual appliance or install vCenter Server in a Windows Server 2008 R2 server or a Windows Server 2012 R2 server, preferably on a VMware virtual machine.
