As described earlier, DG3 are divided into several different components that have different requirements. We therefor divide the requirements into two parts, one for DS and server and one for development.

As you can see, the DG3 server do not require much for working. As long as it's only used for serving one DG3 application and DS, you can run on the lowest level virtual server there is to rent for windows.

The client needs a bit more of the screen and some more memory. The requirements are rather low anyhow. What it need is rights to run it's internal web server. It will automatically take port 8000 for new projects, but you can change it to any port, 80 that is the standard http as well.
