What is an instance?
A Drupal instance refers to a single installation of a Drupal site. It refers to each individual website where the module is active. In the case of multisite/subsite Drupal setup, each site with a separate database will be counted as a single instance. For eg. If you have the dev-staging-prod type of environment then you will require 3 licenses of the module (with additional discounts applicable on pre-production environments).
