Which is perfectly fine - 100 million concurrent users aren't the same for app x and app y, as the business logic the backend run isn't also the same.

Not saying it can't handle everything as well. Just saying the modularity of microservices makes it, in my pov, easier to handle large complex real time systems.

Maybe that's also something that comes with experience - as a rather "newish" guy (professional SE, so one level above Jr), it makes it easier to work on our project.

That's just for the interface layer though.
