## AI overview

This article explains what reverse proxies are, how they process inbound requests, how they differ from VPNs, and how identity-aware reverse proxy architectures can use Envoy and Keycloak. It describes functions including TLS termination, identity-token validation, per-route authorization, path rewriting, and access logging.
