I think the author is somewhat missing the point that the whole Serverless paradigm is not so much about emulating past architectures without servers.<p>It is more about building completely new kind of architectures, where applications are no longer monolithic Node.js/Ruby/whatever server processes, but consist of tiny decoupled components interconnected by evolving systems like AWS Step Functions.<p>This development is dependent on the popularity of static websites, powered by application frameworks like React, which relax the speed requirements of separate REST API servers. Some speed is lost, and a lot of productivity is gained, by getting rid of huge amounts of user-space code and long-running processes.
