  Cilium is an open source, cloud native solution for providing, securing, and
  observing network connectivity between workloads, fueled by the revolutionary
  kernel technology eBPF. Cilium provides network security, load balancing,
  and observability for Kubernetes clusters.

      The Cilium REST API provides access to Cilium daemon and agent endpoints
      for managing Kubernetes network policy, security, and connectivity. The
      API is served by the cilium-agent process over a local Unix domain socket
      and HTTP interface, and covers endpoints, identities, cluster nodes, and
      health status.

      The Hubble API is a gRPC-based observability API built on top of Cilium
      and eBPF that provides deep visibility into network flows, DNS queries,
      HTTP requests, and service communication within Kubernetes clusters. It
      exposes Observer and Peer gRPC services for querying flows, nodes,
      namespaces, and server status across single nodes or entire clusters via
      Hubble Relay.

      The Tetragon gRPC API provides access to eBPF-based security observability
      and runtime enforcement capabilities. It enables querying of kernel-level
      events including process execution, file access, and network activity,
      and supports defining tracing policies via Kubernetes custom resources for
      real-time enforcement and event streaming.

      The Cilium Operator API provides a REST interface for the Cilium operator
      component, which handles cluster-wide tasks such as garbage collection of
      Cilium endpoints and identities, node IPAM management, and coordination
      of cluster mesh operations. It exposes health and status endpoints for
      operator lifecycle management in Kubernetes deployments.

      The Hubble Relay API is a gRPC service that aggregates and relays network
      flow data from multiple Hubble agents running across Kubernetes cluster
      nodes. It provides a single cluster-wide endpoint for the Hubble Observer
      service, enabling centralized queries of flow data, DNS events, and HTTP
      metrics from all nodes through Hubble Relay without connecting to each
      node individually.
