Marc Schreiber. PREvant (Preview Servant): Composing Microservices into Reviewable and Testable Applications. In Joint Post-proceedings of the First and Second International Conference on Microservices (Microservices 2017/2019). Open Access Series in Informatics (OASIcs), Volume 78, pp. 5:1-5:16, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2020)


This paper introduces PREvant (preview servant), a software tool which provides a simple RESTful API for deploying and composing containerized microservices as reviewable applications. PREvant’s API serves as a connector between continuous delivery pipelines of microservices and the infrastructure that hosts the applications. Based on the REST API and a web interface developers and domain experts at aixigo AG developed quality assurance workflows that help to increase and maintain high microservice quality.
