The way I think about this kind of problem is to remember that tools built to deal with huge scaling problems are generally dealing with a very complex set of variables. The tool is going to be designed to let you choose between all of those variables. There's no magic - just configuration whose complexity better matches that of your problem.

That being said, if you are not yet in a situation as complex as the one your tool is designed to deal with, there is a very good chance you will waste some time starting to use such a tool "early." You might get that time back later when you scale, you might have the right people to set up the complex tool the right way for your simple situation, but you are taking a bit of a risk. As long as you go into the situation with your eyes open I think most people end up ok. The horror stories almost always come from people who are working to fulfill needs they do not have and don't understand why their work isn't giving good ROI.
