As for the option of running multiple services on a single machine, this is really a deployment concern. The protocol is still HTTP, so 80/443 should be the default for all services, but some folks will change this to fit their deployment. They could bind multiple IPs and run each service on a specific IP or perhaps someday combine all services into a single process/listening port and route based on HTTP Host header.
