Why is web service good?

Why should we reuse our code? Why should we organize our code in modules? Why should we have the OO concept? All those questions sound different, but there is a single golden thread chaining all of them. The mind set behind them is consistent.

We want to spend less effort to achieve more of our goals, more functionality … In order to do that, we have to analyze and realize all the commonalities behind this wonderful IT world, extracting and well packaging all common solutions, for the greatest possible level of reuse.

We started with reuse of code, now when Internet become more and more tightly connected to our business and daily life, people started to think and modulize the services they put on internet, people started to share services, resources, effort, cost …

This is a trend, and an ongoing trend, but there is one old single golden thread behind it.
