Yeah, but when that happens I usually don't think, oh hey they are lacking an optimal in memory distributed database solution.

I think, well... their engineers suck. Or they don't care. Pick one.

edit: His point is vague, so there is nothing technical to respond to. I am very much interested in a good technical example - but the things mentioned so far are by all appearances relatively straight-forward and linear, hence lack of effort or bad engineering are the only reasonable assumptions left.
