Suppose a restaurant operator intends to do pizza business. He can make his own pizza from beginning to end, but this is more troublesome and requires a lot of preparation, so he decides to outsource part of his work and use other people's services. There are several schemes. One solution is that others provide kitchens, stoves and gas, and you use these infrastructures to bake your pizza. This is the IaaS scheme of popular science before, and another scheme is to provide pizza crust in addition to infrastructure. Just sprinkle your own ingredients on the crust and let him bake it for you. In other words, all you have to do is design the taste of pizza (seafood pizza or chicken pizza), and others provide platform services for you to realize your own design. This is PaaS.
