I doubt a "microservice" has anything to do with delivering the video frames. There are specific kinds of infrastructure tech that are specifically designed to serve live video to large amounts of clients. If they are in fact using a "microservice" to deliver video frames, then I'd ask them to have their heads examined. Microservices are typically used to do mundane short-lived tasks, not deliver video.
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.
