In fact, much of their architecture depends on it. If you need to deal with scaling, there's no answer to questions like "how many..." or "how much..." If those were known numbers, it wouldn't be scaling. Rather, start thinking in terms of "where is" and "how do I" - for example, "where are the expected pressure points in my application" and "how do I let that scale." It's an architectural question, rather than a quantitative one, which is specifically complex to what your application does.
