Today's society and its organisations are becoming ever-increasingly dependent upon Information and Communication Technology (ICT) systems mostly based in cloud data centres. These cloud data centres, serving as infrastructure for hosting ICT services, are consuming a large amount of electricity leading to (a) high operational costs and (b) high carbon footprint on the environment. In response to these concerns, renewable energy systems are shown to be extremely useful both in reducing dependence on finite fossil fuels and decreasing environmental impacts. However, powering data centres entirely with renewable energy sources such as solar or wind is challenging as they are non-dispatchable and not always available due to their fluctuating nature. Recently, container solutions such as Docker and container orchestration platforms such as Kubernetes, Docker Swarm, or Apache Mesos are gaining increasing use in cloud production environments. Containers provide a lightweight and flexible deployment environment with performance isolation and fine-grained resource sharing to run applications in clouds. This project intends to develop scheduling and auto-scaling algorithms for container orchestration within clouds based on the availability of renewable energy.
