Competition for users on a global market is fierce, forcing enterprises to provide for better, faster services while offering the same more cheaply. At the same time, users choose to remain oblivious of the infrastructure behind the service - only demanding that it works. This work presents a policy-based revenue management system for computing clouds. Due to the novelty of the market Cloud providers have not established revenue management systems yet. This will however become a key advantage in prospect of fierce competition. In an attempt to attain a more realistic evaluation to the model, this work uniquely reverts to a browser-based 'Cloud Manager', a serious game designed to record the decisions made by players allowing the model suggested to be uniquely evaluated with both often irrational human decision making, and mathematically sound simulation logic. By employing different policies, benefit can be increased compared to currently often employed standard provisioning mechanisms.
