Static upstreams are used to route request to services listening at fixed IP/Host & Port pairs. Static upstreams can be used to proxy any kind of service, and therefore contain a ServiceSpec for additional service-specific configuration. Unlike upstreams created by service discovery, Static Upstreams must be created manually by users
