vSphere Web Access is the Web interface through which you can manage your virtual machines. vSphere Web Access is installed when you install ESX/ESXi.

As with the vSphere Client, you can use vSphere Web Access to either connect directly to an ESX/ESXi host or to a vCenter Server system. The functionality of vSphere Web Access is a subset of vSphere Client functionality.

The vSphere Web Access console provides a remote mouse-keyboard-screen (MKS) for the virtual machines. You can interact with a guest operating system running in a virtual machine and connect remotely to the virtual machine’s mouse, keyboard, and screen.

vSphere Web Access uses a Web interface and an Internet connection to access your ESX host or vCenter Server system.
