It would also be really simple to sftp a single application to a /cgi-bin/ directory on a shared web host. You don't need to know anything except STDIN and STDOUT, and none of that CI/CD or VCS boilerplate to worry about. Instant web applications. It'd probably be much simpler than using Lambda. I don't have anything against FaaS as a concept, but it almost always leads to crappy operation. The simplest examples of it working are crowded out by the attempts that ended up redesigned as normal applications.
