Reading Time: 2 minutes VMware Horizon Client communicates with the View server, which acts as a broker between the client device and remote desktops and published applications. You enter credentials into Horizon Client, the server authenticates your credentials, and then the server finds the remote desktops and published applications that you are entitled to use. Also if you can use VMware Blast to access your virtual desktop or published applications, a client is usually preferrable to have full features.
