In my opinion, today's manufacturers or companies on layer 7, namely application. Companies use layer 7 for business, in Indonesia, for example, Gojek is an online motorcycle taxi application or platform in Indonesia. If you want to do business in a world like this you have to know what people need (supply). Then you find the solution and turn it into a business. I don't know much about business hehehe You can also use big data or AI for business

Or you can create business in IoT this large scale
