Never underestimate the ability of an organization to throw money at hardware and use things _far_ past their engineered scale as long as the performance is still good enough to not make critical infrastructure changes that, while necessary, might take real engineering.

Though to be fair to those organizations. It's amazing the performance someone can get out of a quarter million dollars of off the shelf server gear. Just imagine how much RAM and enterprise grade flash that can get someone off of AMD or Intel's highest bin CPU even at that budget!
