The VMware vSphere Web Client is the Web-based application that connects users to the vCenter Server to manage installations and handle inventory objects in a vSphere environment.
The Web Client presents a graphical user interface (GUI) featuring an object navigator, the main workspace, and the tasks and alarms panel. Through this GUI, the vSphere administrator can manage and supervise the objects listed in the virtualized data center.
Because the Web Client is based on the Adobe Flex platform, the operating system must have Flash installed. For vSphere 6, the Web Client requires Adobe Flash Player 16 or later. Because the latest Flash version is 11.2 for Linux operating systems, the Web Client is not available on those operating systems.
VMware introduced the Web Client in 2012 when vSphere 5.1 was released.
