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 Management - VMware Host Client.

vSphere Command-Line Interface

A command-line interface for configuring an ESXi host.

vSphere Client

The vSphere Client, introduced in vSphere 6.5 is an HTML5-based client and ships with vCenter Server alongside the vSphere Web Client.

Note:

Not all functionality in the vSphere Web Client has been implemented for the vSphere Client in the vSphere 6.5 release. For an up-to-date list of unsupported functionality, see Functionality Updates for the vSphere Client Guide at http://www.vmware.com/info?id=1413.

See Starting and Stopping the vSphere Components for information and instructions about starting and stopping ESXi hosts and vCenter Server.
