It's OK... it would work.

It could be somewhat more expensive or less expensive to host, and somewhat more or less performant. (You didn't say where the data lives, but if it's in a database and you aren't doing something extra with it, then this layer might not be that important, one way or the other.)

For a 100-user app, I'm guessing the major cost here is the switchover cost. Whether it makes sense or not depends on details of where you are now and what problem(s) this is meant to solve.

No one here knows that (maybe even you don't either?) so we can't really give you an answer, just some general pros and cons of serverless.
