Green Orchestration of Cloud-Edge Applications: State of the Art and Open Challenges

In recent years, Cloud-Edge computing continuum paradigms have received increasing attention to support the deployment of latency-critical and bandwidth-hungry applications enabled by the Internet-of-Things. Meanwhile, the dramatic in-crease in energy consumption of ICT calls for new methodologies to reduce the ecological impact of application orchestration, making it environmentally sustainable. This article conducts a systematic literature review of the state-of-the-art related to environmentally sustainable orchestration of containerised applications in Cloud-Edge settings. Ultimately, it points to open challenges and directions for future work in the field.
