Backend API server for Cilium Hubble UI
Hubble UI Backend is a component of the Cilium Hubble UI. It serves as the API server that bridges the Hubble UI frontend with Hubble Relay, providing service map data and network flow information. The backend queries the Kubernetes API to discover services, pods, and network policies, and streams flow data from Hubble Relay to enable real-time visualization of service dependencies and network traffic in Kubernetes clusters.
