a complete, server-less image with the above end-to-end Web application, we can see that the serverless architecture has the following advantages:1. No need to focus on any server, just focus on the core business logic, 5 minutes to quickly build back-end systems and online, greatly improving the development efficiency.2. Function runs with the volume elasticity, pay on demand, when the created function is not executed, regardless of the fee.3. With

Personal programming prefers refactoring, refactoring can improve the quality of your code and make it clearer to read. However, there is a problem with refactoring, that is, how to ensure that the reconstruction of the implementation of the function with the code before the reconstruction of the same, if each refactoring after the completion of this indifference, there will be great risk, if each refactoring, the side of the
