Delivery of software as microservices running on immutable and self-sufficient containers is a very sobust method and has gained a lot of popularity in the recent years. Containers usually expose tyhe microservice as a web service acccessible through a certain port number on the host. Because host machines are able to run many conatiners and the fact that these containers need to be started and shut down quickly and easily without any side effects, it is not really feasible for consumers of these web services to point to manually assigned hosts and ports.
