Josef,
This may not be possible. There are many Cloud servers and the font would need to be installed on all of them due to the load-balancing. More to the point, if this is a commercial font (that is it has been purchased by the customer) I doubt that the licensing for the font would permit it to be installed on a publicly facing server, since it would then be available to any user of that server.
