I'm not sure what NVC is. If you're referring to VNC, it's a remote desktop access protocol/system that lets you remotely connect to your server if you have a GUI installed on it. For example, if you wanted to set up a remote workstation, you can install GNOME on your server and use VNC to access it.

Usually cloud servers do not have any kind of desktop environment or GUI set up because it takes up resources and is ultimately unneeded as almost everything can be configured and run using the command line.

Thx kamaln.. Yes I meant VNC... If cloud servers do not support VNC but I read somewhere Fx Data Cloud provides VNC. If server OS is CUI and headless then what is need of VNC?
