We only has 8 services and already see the pain of microservices. We are trying to merge some of them. I think micro service is a useful technique, only when use properly at a certain scale. I wouldn't bother doing microservice when team is small and product isn't mature because we still haven't figured out exactly what each service has and may eventually has to duplicate some functionality. With that being sad, I think thing like auth, push notification is absolutely should be their own services.
