At the Cloud Forward Conference 2016 (CF2016), held on October 18-20, at the Circulo de Bellas Artes, Madrid). UBITECH’s R&D team presents a context model for representing the entire lifecycle of reconfigurable-by-design distributed applications consisted of microservices and denoted in the form of a service graph. Based on the context model, we describe a policies management framework targeted at service providers for managing deployment and orchestration aspects of such applications over programmable infrastructure. As a matter of fact, the Policies Management Framework provides policies enforcement over the deployed service graphs following a continuous match-resolve-act approach. Specifically, the match phase regards the mapping of the set of applied rules that are satisfied based on the data streams coming from the monitoring infrastructure, the resolve phase regards the process of conflict resolution -if any- among the satisfied rules taking into account the pre-defined salience of each rule, while the act phase regards the provision of a set of suggested actions by the Policies Management Framework to the orchestrator, responsible for service graphs placement and management. Policies enforcement is realised through a rule-based framework that attempts to derive execution instructions based on the current set of data and the active rules; rules associated with the deployed service graphs over at each point of time.
