A Method for the Quality‐Aware Automated Selection of Deployment Technologies

Domain The deployment of distributed multi‐component cloud applications typically requires a combination of multiple heterogeneous deployment technologies. A different combination of deployment technologies should be chosen due to varying deployment qualities, such as the functional suitability and reliability of the deployment technologies for the deployment of the components. A suboptimal selection of deployment technologies makes the deployment error‐prone. Problem Selecting and maintaining the combination of deployment technologies requires modeling effort and expertise. Contributions We present a method that automatically selects deployment technologies based on a knowledge base of deployment scenarios and corresponding deployment qualities of deployment technologies. Evaluation We show the practical applicability and the usefulness of our method. For the practical applicability, we conduct two case studies based on an open‐source reference architecture application and a real‐world industry application using a prototypical implementation of our method. For the usefulness, we conduct a user study in which participants assign deployment technologies with and without our method. Conclusions Our method is a useful contribution that reduces the modeling effort and the required expertise when maintaining the combination of deployment technologies. Further, our method enhances the deployment quality.
