Why make software scalable while you can scale using cheap hardware and virtualization? Then you can deploy simply and primitive systems built by outsourced global development centers on these new hardware platforms.

I don't really want to start an argument that is off-topic anyway, but with all the overhead
and quirks of virtualisation, performance is actually weird (a new way of describing performance).
