You use the vSphere Client to manage virtual machines. With the vSphere Client, you can open a console to the desktop of managed virtual machines. From the console, you can change operating system settings, use applications, browse the file system, monitor system performance, and so on, as if you were operating a physical system. You can also use snapshots to capture the entire state of the virtual machine at the time you take the snapshot.

You can connect the vSphere Client directly to an ESXi host and work with only the virtual machines and the physical resources available on that host. Connect your vSphere Client to a vCenter Server to manage virtual machines and pooled physical resources across multiple hosts. Multiple vCenter Server systems can be joined together in a vCenter Server Connected Group to allow them to be managed with a single vSphere Client connection.
