Abstract: In a cloud computing market, Software as a Service providers face the Dependent Software Service Distribution Problem, i. e., the challenge of cost-minimally distributing partially dependent software service instances across infrastructure in the form of discrete virtual machines. In the work at hand, we introduce the Software Service Distribution Broker to address this challenge. As integral component of the broker, we propose a mathematical optimization model and corresponding algorithm. An evaluation, which is based on data from actual software services and cloud systems, indicates the applicability of our approach for small-scale scenarios involving approximately 20 software service instances or less, but also illustrates the need for the development of heuristic solution approaches.
