The microservices demo "Online Boutique" [1] (Apache-2.0 license) of Google Cloud Platform is used as a reference implementation (older version). Adaptations and necessary reimplementation were made for a proof of concept for Actor4j Cloud (here, using a single instance approach). For further reading, have a look at the research paper [2].
