I’m genuinely curious about the reasoning behind that statement. It’s very possible that you are using a different set of assumptions or definitions than I am.
I say that because, for performance reasons, you’d never want to wait on potentially several hops to stream media and because the act of streaming could very well be a good enough domain boundary.
That’s okay, you probably just haven’t worked with high performance services or micro services before.
Network requests (sometimes called hops) take a significant amount of time. You don’t want your streaming service to take a significant amounts of time.
In microservices land, you generally try making services based on some “domain” (metaphorical, not like a literal domain name) which defines the responsibility of any given service. Defining these domains is more art than science and depends on the business needs and each team.
Video streaming might be one of those domains for Netflix.
