What serverless does is to force the developer to have a sharp separation of code and persistence. For all cases. Even saving a small inter-request variable that lives for 5 seconds or less. What serverless does is to force scalable architectures. The price is slim to no control over build and execution environment as a consequence of not taking the underlying architecture into account. For many people this is not an issue. These people will be very content with serverless and should definitely use these types of solutions.
