If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.

The content of the website is stored on the source server, and the CDN is the cache of the content. Users are only allowed to access the CDN. If the content is not on the CDN, the CDN sends a request to the source server. In this way, as long as the CDN is large enough, it can resist great attacks. However, this method has a premise that most of the content of the website must be statically cached. For websites (such as forums) with dynamic content as the main content, we must think of other ways to minimize users' requests for dynamic data.

Answer: The similarity of these three modes is that they all serve as an intermediate layer between the client and the real used class or system, which plays the role of allowing the client to indirectly call the real class. The difference is that the application occasions and intentions are different.
