Service to service plus front proxy

The above diagram shows the service to service configuration sitting behind an Envoy cluster used as an HTTP L7 edge reverse proxy. The reverse proxy provides the following features:

• Supports HTTP/1.1, HTTP/2, and HTTP/3.

• Talks to the service to service Envoy clusters via the standard and using the discovery service for host lookup. Thus, the front Envoy hosts work identically to any other Envoy host, other than the fact that they do not run collocated with another service. This means that are operated in the same way and emit the same statistics.
