"I choose Azure PaaS products according to my purpose. The good thing about Azure is that each product has a clear concept and a consistent culture of user-friendliness. All products have the same UI design. There is a line of thought that can not be set more finely. There are times when it is difficult to make detailed settings, but it can be said that it is precisely because there are such restrictions that you can concentrate on how to combine them.”
