> you can scale up the microservice dedicated to serving videos, but not scale up the service dedicated to users signups, which isn't having an increased load.
No, splitting a codebase does not magically make it more scalable in production. You still have to prove that the authentication component would create significant unnecessary load if it was scaled up together with the video service.
