The fact that it is not listening on an incoming network port makes it less of a server IMO. Proxies still proxy things back to another server that is listening for TCP connections, not to a client that has previously initiated a connection to the proxy.
- fyrabanks 7y agoare pub-sub servers less of a server? also, a proxy server is itself a server.
- clinta 7y agoA traditional proxy server is a server and a client. A server to the downstream clients, and a client to the backend servers. Pub-Sub depends on the specific implementation. But anything with an open network socket listening for incoming connections I'd call the server, and anything making outbound connections I'd call the client. In some implementations only the broker is the server. In others every node is a server as they're all listening for multicast discovery messages.
