Technology agnostic

The application interface for a Microservice, or the way we communicate to a Microservice, also needs to be technology agnostic. It means the service needs to use an open communication protocol so that it does not dictate the technology that the client application needs to use. And by using open communication protocols, for example, like HTTP REST (JSON based), we could easily have a .NET client application which talks to a Java-based Microservice.
