Before I left my last company, we were spending about a couple hundred dollars per month just on media storage/bandwidth alone for serving academic papers/docs/data (as well as our logs)… in top 5k in alexa, top 100 in indonesia with about maybe 60-70 customers paying 150-200 dollars per year coming from mostly EM countries… the customers can barely afford/justify spending what we were offering over using some open source alternatives, and there would be no way in hell we'd spend that on just logging.
I at least helped 10x the customers and cut costs from when I joined to before I left (stayed a little over a year)… but man, talk about constraints…
