KAPETÁNIOS: Automated Kubernetes Adaptation through a Digital Twin

This demo presents a self-operating Kubernetes (K8s) cluster that uses digital twinning and machine learning to autonomously adapt its Horizontal Pod Autoscaler (HPA) to workload changes. The demo uses a digital twin of a K8s cluster to gather performance statistics and learn a model for the workload. With the model, the cluster autonomously adjusts HPA parameters for better performance. The demo illustrates this process and shows that the requested pod seconds decrease by ~37 %, while the request latency stays mostly unaffected.
