Pricing Multiple Standalone Installations


I read that the Standalone Installation is totally free when we install it on one single machine.
However, I have the following doubt:

Assume I have 2 completely separated Standalone Installations, each of them running on a separate machine/cloud server.
If each of these installations is serving different applications, do I still have to pay for the 2nd installation?
Or are both installations free, since they are isolated and serving different apps ?

Kind regards,


Both installations would be free if they are completely isolated from each other.


Thanks for your reply Mark!
