A service is scalable when we increase the resources in a system. Increasing performance is serving more units of work. Good service is urgent for all industries.

Is it possible to make a hit counter for a single web page scalable, assuming it is required to be accurate? Ponder that for a while before asserting a complex system is truly scalable.
