Note: Web client is delivered with vCenter - which is not included with this edition
vSphere 5 introduced a web based (Adobe Flex based) vSphere client interface which makes the access to vCenter platform-independent. The initial release was not a full replacement for the classic vSphere client app but with 5.1 it is considered the core management interface matching functionality to the (now) legacy client. It has a customizable interface and allows to view larger scale (i.e. multi vCenter) environments with a single inventory view (without using the old linked mode) through new single sign-on capability.
