cloud computing

If SaaS, PaaS, IaaS is to benefit a company, the scale of economy has to take into play. For a large enterprise, for example, WalMart, it's IT infrastructure is so huge and so big, it just make sense to have its own private cloud. It is not imaginable for a company as big as GE to outsource it's infrastructure to Google.

The shared services will provide scale of economy by its own IT.

If google or others hosting this for them, it might just cost too much for the service.

Private cloud for small and medium business may not make much sense, they can use Google for scale of economy. But as the company grow, the steady flow of cash toward google might have to be stopped.

1. What is self-improve?
2. Is it objective?

For a computer, self-improve is result satisfying the following:
1. Same job faster
2. Same job with less less resources consumption
3. Add new capabilities
4. New solutions that satisfy one or all criteria above: 1-2-3

If all these happens, a computer will be able to invent, and thus, substitute human thinking!


Here is how:

Over the process, the computer will be "smarter" by acquire new capabilities, be "more efficient" by consume less resources, be it energy or space or raw material, and in the same time, provide new solutions, new creation, and make the world a better place to live...
