The expanding universe of services 

The more specialized, layered, mobile, distributed, and connected society (individuals and organizations) becomes, and greater its opportunity costs, and income levels, the greater its dependence on services. 

We need services not just for more kinds of goods we buy and sell, but also for the services. Then we have services that make possible services. And services that make those services possible. So, for every bit of change in society, there is new potential for services, both, on the demand and supply side. 

Micro services add to this growth and expansion, because they’re formalizing the idea of making services more modular, composable, and more thing-like and object-oriented.
