If you are moving your Sage server off premises you are going to want as little latency between where you are running the applications and the Sage 300 CRE server. This will help keep the application from crashing, and will also reduce performance hits from the network. Basic options would be:

- User workstations in the environment. Something like Citrix or RDS would be reasonable answers.

- RDP to the Sage server itself.

From a security perspective I prefer the first option. I would 100% recommend against going over a VPN connection between the location of client installs and your Sage server.

Now that you say it your way I guess 'Windows as service", MS's newer product, may work as well as long as they are in the same tenant.
