About this talk

In this talk, Matthias Bertschy, a maintainer of Kubescape, explores the challenges and solutions involved in scaling Kubescape to accommodate clusters with thousands of nodes. He discusses the recent re-architecture of the aggregated API server, which enables the batch processing of events while efficiently managing resource usage. The session highlights the significant resource demands typically encountered, such as the over 8GB of RAM used when listing all pods with "kubectl get pods" on large clusters. This presentation is particularly valuable for those interested in cloud native computing and the operational scalability of Kubernetes solutions.
