If you want to run a remote service as a VNC server, you’ll need to install the Google Cloud Engine.
Google says it offers this capability through its own Google Cloud Platform, and it’s available as a service.
To use it, you need to have an existing VNC client running, and then add a Google Cloud Service account to your account.
The Google Cloud API enables developers to build apps that work with VNC, Google’s server-as-a-service, or VNC-as a service (VNC-AaaS).
You can also add a new VNC session to your existing Google Cloud account.
To get started, follow the instructions on this Google Cloud Console page.
