Extending Kubernetes API - The Hidden Power of Aggregated Server Objects

Discover how to extend the Kubernetes API beyond Custom Resource Definitions (CRDs) using the lesser-known but powerful API server aggregation mechanism. Learn why CRDs, while flexible and widely used, can create performance bottlenecks when managing large objects like Software Bill of Materials (SBOMs) or high-volume datasets due to their reliance on etcd storage. Explore API server aggregation as an efficient alternative that allows projects like Kubescape to handle oversized objects without burdening etcd. Examine the technical architecture behind this approach, understand specific use cases where aggregated server objects excel, and see real-world implementation examples through Kubescape's practical application of this technology for managing large-scale Kubernetes security data.
