      The Envoy Proxy Administration Interface provides a local HTTP-based
      management API for querying and modifying various aspects of the Envoy
      server at runtime. It serves as a critical operational tool for
      monitoring, debugging, and managing Envoy proxy instances including
      statistics, clusters, listeners, certificates, runtime settings, logging,
      and health checks.

      The Envoy xDS (x Discovery Service) REST API provides endpoints for
      dynamically discovering and configuring Envoy proxy resources including
      clusters (CDS), listeners (LDS), routes (RDS), endpoints (EDS), secrets
      (SDS), and runtime configuration (RTDS). The xDS protocol is the
      foundation of Envoy's dynamic configuration model, enabling control
      planes to push configuration updates to Envoy instances without
      requiring restarts.

    description: >-
      The Envoy Rate Limit Service (RLS) is a gRPC-based API that allows Envoy
      to delegate rate limiting decisions to an external service. When a request
      matches a configured rate limit rule, Envoy calls the RLS to check whether
      the request should be allowed or throttled based on descriptors extracted
      from the request context.

      The Envoy Health Discovery Service (HDS) is a gRPC-based API that enables
      a management server to instruct Envoy to perform health checks on behalf of
      the control plane and report results back. This allows centralized health
      state management across a fleet of Envoy instances without requiring the
      control plane to perform health checks directly.

      The Envoy gRPC Access Log Service (ALS) API provides a streaming gRPC
      interface for receiving access log entries from Envoy instances in real
      time. It enables centralized log aggregation by allowing Envoy to stream
      HTTP and TCP access logs to a remote endpoint rather than writing them
      locally.

      The Envoy External Processing API is a gRPC-based service that enables an
      external server to inspect and modify HTTP requests and responses as they
      pass through Envoy. This extensibility mechanism supports use cases such
      as custom authentication, header manipulation, body transformation, and
      dynamic routing decisions without requiring Envoy filter plugins.

    description: >-
      The Envoy External Authorization API provides a gRPC or HTTP interface for
      delegating authorization decisions to an external service. When a request
      arrives, Envoy calls the ext_authz service, which can approve, deny, or
      modify the request before it is forwarded to the upstream. This enables
      policy-based access control enforced at the proxy layer.

      The Envoy Metrics Service API is a gRPC-based interface for streaming
      Envoy's statistics and metrics to a remote metrics collection service.
      It allows operators to centralize telemetry data from multiple Envoy
      instances, supporting integration with observability platforms for
      monitoring proxy performance and traffic patterns.

      The Envoy Tap Service API provides a mechanism for intercepting and
      recording HTTP and TCP traffic passing through Envoy. The tap filter
      matches requests and responses based on configurable conditions and
      streams the captured data to a sink such as a gRPC service or local file,
      enabling debugging, auditing, and traffic analysis use cases.

  Envoy Proxy is an open-source edge and service proxy that is designed for cloud-native
  applications. It acts as a gateway for all incoming and outgoing traffic within
  a microservices architecture, providing functionalities such as load balancing,
  service discovery, encryption, authentication, and observability. Envoy Proxy is
  known for its high performance and low latency, making it a popular choice for companies
  seeking to optimize their network traffic and improve overall system efficiency.
