## What it is
A Go library implementing the Envoy xDS discovery service APIs (data-plane-api) as a gRPC API server with an in-memory configuration cache. It provides shared infrastructure for building custom control planes that push configuration to Envoy proxies.

## Use cases
- build a custom control plane for Envoy proxies
- serve xDS configuration over gRPC to Envoy fleets
- cache and push Envoy configuration updates to proxies
- implement service mesh control plane in Go
- manage Envoy listener and cluster configuration programmatically
- integrate Envoy config delivery into an existing Go service

## When to choose
- you are writing a Go control plane that configures Envoy via xDS
- you need a production-ready gRPC xDS server with caching rather than building from scratch
- you want to share Envoy configuration logic across multiple control plane implementations

## When to avoid
- you need a turnkey full control plane that translates platform services into Envoy config
- you are not using Envoy or the xDS protocol
- you need a control plane in a language other than Go

## Facets
- artifact type: library
- maturity: active
- function: rpc, api-framework, caching, middleware
- domain: infrastructure-as-code, microservices, networking, developer-tools, apis
- platform: go, cross-platform
- tags: envoy, xds, grpc, control-plane, service-mesh, data-plane-api, web-server
