Evaluation of Cloud Continuum Computing Resources: A Mathematical Programming Approach

The proliferation of Internet of Things (IoT) and advancements in cloud and fog computing have catalyzed the development of the Cloud Continuum, an enhanced cloud system integrating diverse computational resources and services. This paper introduces the Cloud Fog Service Broker (CFSB) designed to facilitate the evaluation and selection of these resources within the cloud continuum ecosystem. The CFSB employs Multiple-Criteria Decision Making (MCDM) methods that rely on Mathematical Programming to assess resources based on multiple factors. This integration allows for a comprehensive assessment, ranking resources by synthesizing these diverse criteria and incorporating user preferences through weight restrictions in optimization models. The architecture, criteria, evaluation process and an illustrative example of the CFSB's application highlight its role in decision-making for cloud resource selection.
