Client Interfaces for vSphere
You have several ways to access vSphere components through vSphere interface options.
vSphere interface options include:
vSphere Web Client
The vSphere Web Client is a Web application installed on a machine with
network access to your vCenter Server installation. The vSphere Web Client
is the primary interface for connecting to and managing vCenter Server
instances.
VMware Host Client
The VMware Host Client is a Web-based application that you can use to
manage individual ESXi hosts that are not connected to a vCenter Server
system.
For more information about the VMware Host Client, see vSphere Single Host
