Envoy Proxy Health Discovery Service API is one of 25 APIs that [Envoy Proxy](https://apis.io/providers/envoy-proxy/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Discovery, gRPC, Health, and Proxies. The published artifact set on APIs.io includes API documentation, an API reference, and a GitHub repository.

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.
