So everyone wants to have the ultimate system that never breaks can handle 'all' the users and shows no strain when doing so. How do you accomplish something like this? Well you could hire developers that know all the best ways to do everything, experts in everything related to configuring applications to run the best that they can on the hardware and software it sits on but what's the odds of that happening. The other option is to have a bank account that is never ending and throw 'all' the hardware at your application to make sure it doesn't ever have a slow day but then how are you making your money, how do you know when 'all' the hardware isn't enough.
